The movie Chain Kulli Ki Main Kulli revolves around the life of a thirteen year-old orphan boy, Karan. He has been brought up in an impoverished orphanage, hearing from his caretaker stories about India's victory in the 1983 Cricket World Cup under the captain ship of Kapil Dev.
One day, he finds an old bat with the year '1983' engraved on it. Karan fantasizes that the bat found by him is the same bat which Kapil Dev had used during the 1983 Cricket World Cup matches. He believes it to be his lucky bat. On one fortunate occasion, the coach of the Indian cricket team spots Karan playing. He is highly impressed with Karan's batting skills and selects him as a member of the Indian cricket team.
Karan's bond and belief with his lucky bat grows stronger and it becomes his magic bat for him. Everyone congratulates Karan for his good performance in the cricket match except his orphanage mate, Raghu. He feels jealous of Karan's newly achieved success. To hinder his success, he breaks Karan's lucky bat during the India-Pakistan innings. Consequently, the incident becomes a huge setback for Karan and he refuses to play without his magic bat. This is the time when he is made to realize that the magic was not in his bat, but inside him. Thereafter, Karan plays well and his team wins the match. At last, Karan develops confidence in his own capabilities rather than depending on his magic bat.
