This off-beat story combines elements of a science fiction adventure and World War II drama. A platoon of U.S. soldiers are surrounded by the enemy in Italy and are forced to fight their way back behind the lines to their troops. The platoon is populated by the usual characters: "Sarge" (Tim Thomerson) is not afraid of anything, Joey (Timothy Van Patten) has not totally left childhood behind him, and Dolan (Biff Manard) is an aggravating reporter out for a headline. When the soldiers encounter a spaceship on their way back to safety, the plot takes a 180 degree turn. Zone Troopers' novel premise is matched by the cast, who deliver good work throughout.
