John Winger (Bill Murray), a hard-luck cabbie, enlists in the U.S. Army after losing his job, car, apartment and girlfriend in one day. He convinces his friend Russell Ziskey (Harold Ramis) to join him. During basic training they endure repeated arrests, clashes with their drill sergeant (Warren Oates) and a chaotic incident at a mud-wrestling match. Their misbehavior peaks when they steal a top-secret vehicle to date female MPs and end up behind enemy lines, sparking an international scandal.
