Mid-1980s sci-fi horror spoof. Catherine Mary Stewart and Kelli Maroney star as Reggie and Samantha, two teenage Los Angeles sisters who wake up one morning to discover that everybody in the city has been turned to dust by a comet except them and truck driver Hector (Robert Beltran). The trio must now fight their way through the deserted city, battling flesh-hungry zombies and a bevy of evil scientists in their frantic bid for survival.
