Bongoman's ill-tempered mother-in-law arrives for a visit. Bongoman is far from thrilled as he doesn't see eye-to-eye with the old lady. She never has a kind word for him, calling him a good-for-nothing bum. The tranquillity of the Bongoman household is turned upside down as the old lady imposes her uncompromising will, harassing Bongoman at every given opportunity, especially his evening forays to the neighbourhood pub. With no peace of mind, Bongoman pushes back and devises a series of tricks to force her out of his house. None of the tricks work out and Bongoman finds life unbearable in his own house. He reports an assault against him by his mother-in-law to the police but finds himself in jail as the perpetrator of the assault. Bongoman storms out of his house in protest after a brief interlude in jail, taking up residence in the local park, where he has to contend with some unsavoury night-time characters for rights to the more comfortable sleeping spaces and has to fight to assert his position in the pecking order. How will Bongoman rid himself of this terrible relative? Does he have any more tricks up his sleeve?
