Directed by Badri, Aindham Padai is about two feuding families that simply cannot agree on any terms. Gunasekaran (Nasser) is the oldest of five brothers. He gets his brother Karunakaran married to Devasena (Simran), who is an immature and spoilt daughter of doting parents. She mistakes the marriage alliance to be with Prabhakaran (Sundar), who turns down the proposal. Simran is insulted and vows to take revenge on the brothers.
