Steve Martin is the inexplicable, the incorrigible, the invincible Sgt. Ernie Bilko, leader of a ragtag group of the sorriest soldiers ever to enlist in the armed forces. Instead of training his troops for battle, he passes on his legacy of gambling and shunning responsibility. Times get tough however, when the base is threatened with a shutdown, and a by-the-book adversary, Major Thorn (Phil Hartman), is intent on taking Bilko's reputation down with it. Now, all bets are on Bilko to drum up his biggest scheme yet to save Fort Baxter... and clear his name!
