The Ending Of Cosmic Sin Explained
We take you now to the year 2524, in an era replete with space stuff. Folks are colonizing space, living in their colonies in space, and blowing up the colonies where other people live in space. Space: It's where it's at, no doubt about it.
One gruff son of a space gun who has made a name for himself as an exploder of his fellow space folk is one James Ford (Bruce Willis), better known as "The Blood General," who killed 70 million colonists through the use of a Quantum Bomb during an attempted secession. That the name "The Blood General" implies the existence of a "Blood Specific" is a matter for another day. "Cosmic Sin" is only 88 minutes long, so there isn't a lot of time for hilarious "Unbreakable" logic tomfoolery. The takeaway here is that Ford wound up at the business end of a redemption arc well before the movie began.
Luckily, he gets a chance to make good when humanity is attacked by the Sigea, aliens with the ability to control people's minds through the liberal application of black goop. With the promise of whatever the opposite of a dishonorable discharge is — let's say an honorable recharge — Ford teams up with a scrappy group of fellow explosion enthusiasts to give the Sigea what for in a little maneuver called "Operation: Cosmic Sin."
Cosmic Sin and the good-hearted use of Earth-shattering kabooms
Earth's small bevy of intrepid heroes travels to the colony of Ellora, where they intend to cut off the Sigea attack before it can get any further. There, they're assisted by a contingent of survivors, who escort them to the ol' orbital cannon. The plan: Launch a Quantum Bomb — the same sort that James "The Blood General" Ford dropped in exchange for his cool new nickname — into the transpacial gateway above the planet, sealing it off and keeping those pesky brain control aliens out of Earth's hair for the foreseeable future.
Things start to get more complicated from there. The Sigea are onto the squad's plan, and start closing in on the orbital cannon, utilizing a black-gooped former member of the team to communicate their nefarious intentions. From there, it's thrill-a-minute, self-sacrifice-heavy last stand time for Earth's plucky last line of defense.
The team manages to launch the Quantum Bomb into Sigea space, and the day is saved. While it's not explicitly stated that Ford gets a new nickname like "The Helpful Alien Killer General," it's nice to imagine that he did. The remaining members of the team drink at a bar. In the end, the film reminds us that sometimes, detonating a giant bomb gets you in a bunch of trouble, and sometimes it gets you invited out for shots. Like life, "Cosmic Sin" is complicated.
