An ironic look at a climber who decides to do anything, including throwing mud at his best friend, to get a job he thinks will launch him into a better career.

As a result of a mistake, the siblings change roles and go on vacation somewhere else than planned. The boy goes to his aunt and cousins, the girl goes to her uncle and cousins. To save her brother, the sister pretends to be a boy and he, left with no choice, pretends to be a girl.
