Ver PelisPlus. In this film with its humorous undercurrent, a widower rents the upper floor of the house of a young couple, who can no longer afford the mortgage after a dismissal. The man immediately moves in. The only thing he brings with him - hidden under a cloth - is a large cage. Acting against the man's express warning, the couple goes up to his room when he is away. Their curiosity costs both them and the tenant dearly.
