A Filha dos Trapalhões (1984)

The Trapalhões live in a floating boat and have a miserable life. When they find an abandoned baby, they decide to raise it as if it were their own daughter. Later, when they begin to work in a circus, they discover that the child is in fact the daughter of the trapeze artist and that she was forced to surrender her daughter to a gang that negotiates children abroad. This gang finds them and tries to recover the girl who now, however, has the help of the Trapalhões to protect her.
