Dono, Kasino and Indro lose their pants while they are defecating in a public toilet at an entertainment spot. As a last resort to cover up his embarrassment, Dono steals the pants of the man in the stall next to him. As it turns out, this man is the father of three young women that Dono, Kasino and Indro start going out with. The story, which is little more than a bunch of skits wrapped up together, starts from here.

Dono, Kasino and Indro (the Warkop DKI comedy trio) are waiters at a restaurant owned by the parents of Yully, the girlfriend of Kasino. They are specially hired to compete with a rival restaurant owner, Soleh, who likes to sabotage Yully's father’s restaurant. Many slapstick antics such as catching a rat that falls from the attic, start the comedy rolling. Then the journalists and the police start watching Soleh, and that finally leads to his arrest.
