When Santa and a couple of kids are kidnapped and Christmas is threatened by Martians, Santa and the kids help sort it out.

Santa Claus Conquers the Martians -- When Martian children get to see Santa Claus only on TV, their parents decide to abduct Santa to make them happy.

When lounge singers Sam (Sam Rockwell) and Eddie (Steve Zahn) are mistaken for ace safecrackers, they reluctantly enter the criminal underworld in this madcap farce from writer-director John Hamburg (I Love You, Man, Along Came Polly). Jewish gangster Big Fat Bernie Gayle (Michael Lerner) sends Veal Chop (Paul Giamatti) to con real safecrackers (Mark Ruffalo and Josh Pais) into service, but the henchman mistakes the singers for the crooks.

The Martians are irked that their children spend so much time watching TV shows from Earth that sing the praises of Santa Claus, so they decide to make a trek to the planet to capture Mr. Claus. During their mission, they also abduct two children who lead the aliens to the North Pole and Santa. The Martians take all three earthlings back to Mars, where, with the help of a native, they manage to spread Christmas cheer throughout the red planet.
