Siva(Prashanth) is admitted to a medical college in Chennai and his father(Rajesh), a police constable, gets a tranfer to Chennai too so that he can keep an eye on Siva. He develops a liking towards Mahalakshmi(Sneha), his collegemate. But Naga(Subburaj), Maha's servantmaid's son, is obsessed with making Maha his own.

Sakthi goes to Aravangadu to sell his father's property and gets into the Singarayar household as a guest, not realizing that the family wants him dead owing to a family feud. But, they will murder him only when he steps out of the house to uphold their hospitality. Can Sakthi manage to stay alive?
