Vedigundu Murugesan (Pasupathy) is a small-time guy who breaks the law occasionally but is a Good Samaritan in the eyes of the local judge (Nirmala Periyasamy) as he provides shelter and looks after a mentally challenged girl named Ponni (Deepa Shankar), who was deserted by her parents.

A lady constable named Nachiyar (Jyothirmayi), who rubs Murugesan the wrong way, falls in love with him due to his humanitarian nature and the will to help others.

Parallel narration is the comedy track of Alert Aarumugam (Vadivelu), a petty and clever thief.
