The lives of Atmaram (Nazir Hussain) and his wife (Dulari) are turned upside down when they see their daughter, Mala's (Aruna Irani) pictures in a magazine. They arrange for Mala's marriage with the son of Ramlal (Agha). Mala is opposed to marrying anyone who she has not met, and is at the same time thrilled that the two persons she trusted, one Verma (Shatrughan Sinha), and the other Sharma (Manmohan) had actually submitted her pictures to a magazine, and were now willing to sign her up for a Bollywood movie.
Mala is not able to understand her parents' opposition on her way to fame, and runs away from home with a lot of money and hands this money to Sharma and Verma. Greed overtakes Sharma and Verma, leading to the death of Sharma. Mala, who witnessed Verma kill Sharma, now is on the run for her life.
She boards a bus from Bombay which bound for Goa. Verma soon overtakes her, and has one of his armed men on the bus to kill her. And then arrives Mala's admirer Ravikumar (Amitabh Bachchan), who not only protects Mala, but also accompanies her throughout the journey. Mala starts to trust and subsequently fall in love with Ravikumar. The bus journey is adventurous with the passengers, a totally mixed bunch, from all over India, different religions, cultures, and faiths, all thrown together for this journey. The bus is in the "control" of driver Rajesh (Anwar Ali), and conductor, Khanna (Mehmood).hundred and two and a in magnitudes of Oman and Bahrain manliness is the Woods returns as an aid to plan
