The Best Quantum Leap Stories

"Quantum Leap" follows Dr. Sam Beckett (Scott Bakula), a time-traveling adventurer, as he attempts to correct the mistakes of the past. This unique premise allows the series to explore entirely different settings, casts, and dilemmas in each episode. Through it all, Sam Beckett acts as the series' anchor: No matter where or when he is, he remains humbly and heroically dedicated to his mission, whether that means facing down gangsters or rescuing lost children.

Though "Quantum Leap," which first hit the small screen in 1989, might seem a bit dated to modern eyes, it remains a uniquely entertaining work of sci-fi storytelling. Through five seasons and nearly 100 episodes, the show mixes melodrama with old-fashioned light-heartedness. Though you might expect this to result in something groan-inducing, in fact, "Quantum Leap" is resolutely charming. It was also one of its era's most intriguing shows, as viewers never knew what kind of story they'd be getting each week. Curious which installments of this beloved series are the absolute best? Look no further: These are the best stories from "Quantum Leap."

In this episode, Sam inhabits the body of Jesse Tyler, a Black chauffeur living in Alabama circa 1955. He must save the life of Jesse's elderly employer, Melny Trafford, widow of the former governor. Al, who witnessed the brutality of this period firsthand, warns Sam how dangerous it is to be Black in Alabama at this point in history. "The Color of Truth" soon becomes about more than simply saving Trafford's life, especially after Sam angers the townspeople by sitting at a whites-only lunch counter.

This episode doesn't present the most nuanced commentary on racism, and often portrays bigotry as being solely a thing of the past. Yet it still manages to make a much-needed statement about the viciousness of intolerance. In one particularly moving scene, Melny tells Sam that segregation is "just the way things are and the way things have always been." Sam replies, "Maybe it's times things changed." That's a message that is still needed today. This episode is also notable for featuring the first time Al is observed by a person in the past.

Arriving on April 1, 1969, Sam inhabits the body of Jake Rawlins, a Chicago detective, in this episode. Al tells Sam he's there to stop a married woman named Beth from meeting and falling in love with a man named Dirk Simon, who she'll meet during a chance encounter later that day. Beth's husband has been declared missing in action in Vietnam, but in truth, her husband has been taken prisoner. When he's released in 1973, he will return to find that Beth has moved on and married Dirk, leaving him heartbroken.

Al becomes noticeably obsessed with Sam completing this mission. He claims this is because he went through something similar when he served in Vietnam, but it's eventually revealed that Beth is, in fact, Al's ex-wife, and that Al himself is the husband who is missing in action. In addition to being a heartfelt story in which Al attempts to avoid the trauma of losing his wife to another man, it also sets up his time as a POW in Vietnam, which echoes through the rest of the series.

In the second part of "The Leap Home," Sam is Herbert "Magic" Williams, a member of Tom's platoon in Vietnam. The date is April 7, 1970 — the day before Tom Beckett will die. Sam is convinced he's there to save his brother's life. Why else, he reasons, would he be sent so close to him, in consecutive leaps?  But Al's computer is uncertain. The odds are just as good that Sam is there to complete the platoon's rescue of a group of POWs. Before long, it becomes clear that completing this goal will mean letting Tom die.

Unfortunately, the computer doesn't have enough information on Tom's classified mission to help them know what goes wrong. In a clever move, Sam gets an embedded reporter, Maggie Dawson, invited to join their mission, in the hopes that she'll write a story that will appear in newspaper archives Al will be able to reference. But this trick gets Maggie killed, leaving Sam guilt-ridden. Given the uncertainty at hand, Al chooses to help Sam save his brother.

The episode's final twist is one of the show's most memorable. Maggie's posthumously published photos reveal that one of the POWs Tom would have rescued is Al. This means that Al helps Sam save his brother, at the cost of his own freedom.

Role reversal episodes are a great way of forcing characters to face new challenges. In "The Leap Back," a lightning strike forces Al to become the leaper and Sam the holographic assistant. Al, who often gripes at Sam for how easy he thinks his missions must be, quickly finds out just how hard they truly are to accomplish. Simultaneously, Sam must guide Al without a computer to help him. At first, Sam happy to be back in the present ... until he discovers that the lightning strike has also trapped him in the holographic imaging chamber. After some clever time travel tricks (something this TV show truly perfected), he is released into his old life, earning a rare glimpse of the present day.

In this episode, fans get to spend time with Quantum Leap scientists like Gooshie, a project analyst with a brief appearance in the pilot, who are working feverishly to fix the problem at the center of the series. Sam also gets to talk with Ziggy, the snarky computer that runs Al's handlink computer. But most importantly, Sam finds himself back in his own life in this stirring installment. Having returned from being trapped in the past, he must confront the life he left behind — including the wife amnesia erased from his memory.

In this still-timely episode, Sam takes on the role of Katie McBain, a young woman of 1980 who has been sexually assaulted and beaten by high school athlete Kevin Wentworth. Sam must make sure he sees justice for his heinous crime, but unfortunately, Kevin is the town's golden boy. The community is unwilling to accept Katie's version of events, especially since Sam — as Katie — cannot testify to what happened, because he wasn't there. 

The twists and turns of this story occasionally strain the bounds of credulity, but Sam and Al take Katie's story and situation seriously. Sadly, this is often not the case in television, or real life.  While the ending feels a bit like a cop-out to avoid a completely dour (and, alas, more realistic) ending, "Raped" is nonetheless another "Quantum Leap" episode that successfully tackles an uncomfortable topic through a powerful premise. The seriousness and sensitivity with which it handles its subject matter remains notable, even today.

For five seasons, Sam Beckett is driven by an unknown force, leaping from life to life in an increasingly futile attempt to get home. Along the way, he saves people from untimely deaths, alters fate, and makes right what once went wrong. The series finale, Season 5's "Mirror Image," caps off its magical run with a brilliant mixture of the ambiguous and the definitive, cementing the show as required viewing for any fan of sci-fi TV.

There is no mission to complete in "Mirror Image." Instead, Sam finds himself in a bar that feels foreign, but also strangely familiar. Shockingly, when he looks in the mirror, he sees himself — he hasn't leaped into a stranger. While this sci-fi drama is often filled with wacky technobabble and genre-specific twists, "Mirror Image" instead dips into the well of philosophy and metaphysics, exploring ideas more familiar to scholars and saints than family TV writers. Ultimately, it leaves audiences without the big-red-bow conclusion many expected: Sam never leaps home to resume his life. But the audience knows that he has chosen to continue leaping. This episode pulls together pathos, joy, and mystery in such a wholly unexpected and rewarding manner that viewers have been discussing it ever since it aired.
