The film begins as two slackers, Bones Conway and Jack Kaufman work at "Crazy Boys" discount electronics store in Glendale, California. While they goof off on the job, both have aspirations of opening their own electronics store in the future. Both are fired though, after destroying a rack of television sets. Looking to score some quick start-up money for their store, and believing that the commitment will be minimal, the two join the United States Army Reserves. Bones chooses water purification for their field since his brother was an experienced pool man and the field appeared to be devoid of combat. After surviving basic training, they attend water purification training. The two meet up with Christine Jones, a female recruit longing forinfantry, and Fred Ostroff, a skittish dental student. The foursome adopts the nickname of "waterboys". The group then returns to Glendale. What Bones and Jack do not realize, however, was that Libya has been planning an invasion of Chad, and they are consequently called up for service overseas. They first try to get a military discharge by pretending to be homosexuals, but they fail. Upon arriving in Chad, the four do not get along well with the full-time soldiers, particularly Special ForcesStaff Sergeant Stern. On a routine mission to resupply a forward base, their convoy is ambushed by a Libyan commando squad. The misfit reserves are thought to have been killed in action and are left to fend for themselves. After a few days lost in the desert, they are captured by the Libyan forces and spend a night in a Libyan POW camp. There the reservists meet up with Staff Sergeant Stern who has been shot and captured in an ambush. He briefs them on his failed mission to rendezvous with two HALOedFast Attack vehicles and destroy mobile Scud launchers carrying missiles armed with chemical warheads aimed at American bases in the region. During an airstrike, the four reservists and Stern escape and find the Fast Attack vehicles. They make contact with the American headquarters and are ordered to finish the Special Forces' mission. After locating the missiles, they have a difficult time holding off a battalion of Libyans while painting the missiles with a laser for an incoming airstrike. The airstrike goes off-target, forcing the reservists to destroy the missiles themselves. Bones grabs an AT4anti-tankrocket launcher and destroys the Scud launcher base in one hit, but not before accidentally firing one rocket backwards, forcing the group to use the last rocket they have. The "waterboys" return home as heroes. At the end of the film, they open up their electronics shop next to an Army recruiting station — where two men like themselves are looking skeptical about joining the reserves.

The consensus states "This 1994 Pauly Shore vehicle stretches its star's thin shtick to the breaking point with a laugh-deficient screenplay that borrows shamelessly from Bill Murray's far superior Stripes".
