Advocate Kurishummoottil Mariamma is known for her versatile rhetoric and volatile temper while in court. Her only son is Vava, a proud and arrogant brat who looks after the family farm when he is not engaged in fisticuffs in the neighbourhood. Though he is the village bully, in front of his mother he is as tame as a house cat, and never does anything against her wishes. Pothen Vava tells the story of the relationship between the two, and promises to have an ample dose of action, humour and melodrama. Mammootty plays the role of Vava, while pop diva Usha Uthup does the role of his mother. Joshy, who has directed the largest number of films with Mammootty in the lead, is teaming up with the star after a gap of five years. Their relationship is as old as their film careers. Their first film was Aa Raathri. Their last joint venture was Dubai. This will be Usha Uthup's first feature film.
