Ganga, Jamuna, Saraswati, three sacred rivers in India meet at Allahabad and
this meeting place is called Sangam. Sunder (Raj Kapoor), Gopal (Rajendra Kumar)
and Radha (Vyjayantimala) are three childhood friends. Although Gopal and Radha
have always loved each other, Sunder is oblivious to this and always compels his
friend Gopal to ask Radha's parents to let Sunder marry Radha. Radha's parents
reject Sunder's proposal on the grounds that he is a drifter and is not capable
of supporting their daughter after marriage.
