The film follows a prison warden (played by Charles Janssens) who is utterly miserable because his prison is empty. When Max (played by Paul Cammermans) is mistakenly arrested for murder, the warden is thrilled to finally have a "guest." A delightfully absurd situation ensues, with the warden looking after his prisoner like a doting father. In the end, Max is proven innocent and marries the warden’s daughter. Based on the play of the same title by Jos Janssen.
