When it is discovered that an enormous comet is on a collision course with Earth, a handful of Americans make different preparations for the end of the world. While Leo Biederman (Elijah Wood), the fourteen-year-old amateur astronomer who discovered the comet, deals with the pangs of first love, an ambitious newswoman (Tea Leoni) attempts to reconcile with her estranged parents. Simultaneously, a former astronaut (Robert Duvall) finds himself in the stars once again in an attempt to prevent the catastrophe from occurring. Mimi Leder (THE PEACEMAKER) directs from a script by Bruce Joel Rubin (GHOST) and Michael Tolkin (THE PLAYER).
