A shitty bar-singer bangs an alien woman and contracts a sexually-transmitted pacifism superpower. Can he sing enough to prevent a nuclear war, particularly before the evil aliens track him down and dispose of him?

From a galaxy further than far, far away, comes a movie of solar proportions with a stella soundtrack. Tyler hates life - his rock band are going nowhere, the world is collapsing and girls don't take him seriously. BUT all of that is about to change when a sexy space siren seeks Tylers singing to snuff out the growing stream of violence. Adding fuel to the fire is Freaky Fiend fixed on frying our planet - it's up to Tyler and his musical troupe to turn the tables and restore the name of rock and roll.
