Lineman Sivankutty (Mukesh) falls in love with Parvathi (Annie), but her headstrong mother Subadra (Zeenath) opposes the relationship, citing the reason that her own husband, who used to be a lineman, had dumped her. Shortly afterwards, Subadra's husband Naryanankutty (Janardanan) returns after 18 years & fixes Parvathi's marriage to a junior engineer, while Subadra gives her word to give Parvathi to Aniyan Thampuran, the rich debauchee of the famed Illickal family, complicating things further.
