Injakkadan Mathai & Sons

Injakkadan Mathai (Innocent) & sons Thankachan (Suresh Gopi) & Roy (Jagadish) run a gainful cloth shop while a rival store run by the Chungathara family is at a loss, much to the latter's ire. After Thankachan weds Beena (Saranya), daughter of an old pal of Mathai, Thommichan, Chungathara misleads David (Rajan P. Dev), Beena's uncle, into thinking that Mathai had killed Thommichan. Hearing this, Beena's sister Shirley (Urvashi) moves in with Mathai's family, to take revenge for her dad's murder. (Summary by iceblox)
