Arjun (Jayam Ravi), an unemployed youngster, and Deva (Rahul Dev), a powerful don, both fall in love with Sailaja (Shriya Saran), a middle-class beauty, at the same time on a rainy day at a railway station. Arjun keeps bumping into Sailaja coincidentally every time it rains. This makes them both feel that it is the rain that keeps bringing them together, and they start to fall in love. Deva takes the backdoor route to get Sailaja, with the help of her good-for-nothing father Sundaramoorthy (Kalabhavan Mani). After learning of Arjun and Sailaja's love, Deva and Sundaramoorthy work up devious plans to break them up. They soon succeed in creating a rift between the two lovers. Though Arjun realizes what is really happening, Sailaja falls prey to Deva and her father's foils. The young lovers part ways; Sailaja becomes a leading lady in the movies, and Arjun works with his uncle (Rajesh (actor)) in a quarry as a demolition expert. Deva is cheated out of some money by Sundaramoorthy, and he finds out where Sailaja lives and kidnaps her. Sundaramoorthy realizes that the only person who is daring enough and cares enough to get his daughter back is Arjun and goes to him with his pleas. It takes much convincing, but Arjun decides to rescue Sailaja but for reasons other than love. At this point, Sailaja begins to realize that her father lied to her and tries to get back with Arjun, but he refuses because she did not trust him. Sailaja convinces Arjun that it was not her fault, and they both start loving again. The climax is a heroic fight between Arjun and Deva, in which Arjun is the victor. In the end, Arjun unites with Shailaja.
