Laltu is a spoilt brat who plays nasty tricks and is a part of a gang that commits a burglary. Yet he sings, has a lady love in Poly and a genuine mate in Madhab. He discovers the illegitimacy of his birth at the prime of his youth before he meets his mentor, Dr Bishwaroop, under the most bizarre circumstances.

Laltu's prospective mother-in-law traps him into attaining a near-impossible goal to marry Poly, and he accepts the same in a surge of temerity. In spite of being ridiculed, he carries ahead with his task with occasional encouragements from unexpected corners.

Does he succeed in his mission? More importantly, does he get the hand of Poly?
