In 1944, Dr. Roy Jamnadas, who is working on the theory of nature vs nurture, separates two sets of identical twins he finds at the doorstep of the orphanage he runs and gives them up for adoption to two different families, based in two different cities of India. One twin from each pair is given to a couple in Ooty and the other twin from the pair to a couple in Bangalore. Coincidentally, both the couples name the twins Roy and Joy, after Dr. Roy and his own adoptive brother Joy. Roy 1 and Joy 1's father runs a circus and after his death, they both take up the responsibility of running the circus. Roy 2 and Joy 2's father is a wealthy industrialist. Roy 1 has a strange connection with electricity and electric currents do not affect him. He uses this ability to show tricks at the circus and becomes famously known as 'Electric Man'. Elsewhere, Roy 2 receives electric shocks whenever Roy 1 comes into contact with electricity.
The story then moves forward 30 years. Roy 1's wife, Mala, cannot conceive and wishes to adopt a child from the Jamnadas Orphanage, but Roy 1 is against the idea. Roy 2 is in love with Bindu but her father, Rai Bahadur, is skeptical about him as he has seen Roy 1 with Mala in Ooty and has mistaken him for Roy 2, thinking that he is cheating on Bindu. Roy 2 and Joy 2 come to Ooty to buy a tea estate and there is a lot of confusion and misunderstanding as people mistake them for the other pair of twins. Three robbers - Momo, Mango and Chikki - are after them to rob their money. They back off when Roy 2 gives them electric shocks and their boss, Polson Dada, later comes to take revenge. They also come across Nagmani, the shady cab driver and Bagheera, a dacoit turned hotel owner. Roy 2 thinks they are all part of a criminal gang who want to rob them, and when they happen to come across Mala, they think that she is the leader of the gang.
Roy 1 decides to gift a diamond necklace to Mala but the jeweler mistakenly gives it to Roy 2, creating further confusion. Moreover, Rai Bahadur is now convinced that Roy 2 is married to Mala. On hearing this, Bindu threatens to end her relationship with him, not knowing that Mala is actually Roy 1's wife. All the confusion is cleared when both pairs of twins come face to face at the circus and Dr. Jamnadas reveals the truth to them and his real intention behind separating them. They all reconcile with Roy 1 and Mala finally adopting a child from the orphanage while Roy 2 and Bindu plan to get married soon.
