[2] One of the earliest Bollywood films to deal with "lost and found" formula, Do Ustad revolves around two brothers separated in their childhood who grow up to become thieves.

After this, Jagannath is shown to be a seasoned criminal who has made a fortune by robbing places and he leads a team now.

Jagannath steals a necklace worth ₹12 lakhs (₹1.2 million) and the police want to catch the thief.

The first time the two brothers meet is when Rajan tries to pick the pocket of Jagannath after leaving jail, though the two of them are unaware of each other's identity.

She lands at the place where Rajan and Jagannath stay and all want to get hold of her as her uncle has announced a reward for anyone who might bring her home.

When she tells Jagannath's wife the real identity of her husband, she refuses to believe her, so she hatches a plan instead.

When Rajan comes to take Raja back, Madhu learns the truth and their relationship improves.

Meanwhile, a party is organised by Jagannath in the honour of a well-to-do person from a place, who is actually Rajan in disguise.

Jagannath is freed from jail as he desperately wants to see his son, but in the process is shot by the police.

[6] Uma Vasudev of Thought was unenthusiastic about Do Ustad and called it "a second-grade version of Shree 420".

[7] Among the actors, she found Kapoor ("repeating his Shree 420 image") and Mukhtar ("ill-adjusted in his role") unconvincing, but Madhubala "delightful".

[3] Do Ustad has been remade two times: in 1966 as Iru Vallavargal and in 1974 as Haath Ki Safai.
