Anandakuttan & his uncle Keshu (Jagathi Sreekumar) go to Tamil Nadu to meet Anandakuttan's long-gone sister Anandavalli (Shobha Mohan) who had eloped 20 years ago with a Tamil. Anandakuttan brings back Anandavalli's daughter Parvathi (Roja), who takes a fancy to him & wants to marry him per Tamil customs. Parvathi's cousin Kannayya follows suit from Tamil Nadu, to take Parvathi back & to cut off Anandakuttan's leg - a promise Kannayya made to Parvathi's dad Thirupathi Perumal (Kalabhavan Mani).
