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.
Unfortunately the movie Girl and Boy is not yet available on HBO Max.
