Chandru (Arya) and Bigilu (Lal) are close friends. Chandru is an expert in auto race and Bigilu, a mechanic is an expert in customizing the autos to run at a dream speed of 130 km/h.
Son of Gun (John Vijay) is the chief of rival group who wants to outsmart Chandru-Bigilu group. Chandru, the race champ tries to settle his dues for his auto through a race, which is almost a cakewalk for him. He and Bigilu challenge Son of Gun to a race. And the day for race is fixed.
Bigilu meanwhile introduces Chandru to his sister running a Biriyani shop. Chandru is attracted towards her daughter (Pooja), and woos her into his fold. The affair grows stronger and ends in sex. The care free auto driver however, is not interested in long term commitment and tells it on the face of the girl.
Shocked Pooja curses him and moves away from him. The champion gets distracted on the D day because of the memories of his love affair and fails in the race. He looses his auto and later his dearest friend Bigilu, who comes to know about his affair. The sub plot of the search for the missing diamonds by a smuggler adds flavour to the proceedings. The unpredictable and fun filled climax puts everything in order.
