Mem Didi was loved by everyone in neighbourhood. She was doing various odd jobs, day in and day out so that Rita(Her child, as everyone believed it) could live in comfort and finish her education in Simla and then get married into a good family as she promised to her dying parents at whose place she was a maid. Till now Mem-Didi is struggling all by herself. But it is different now. Sherkhan and Bahadur know her secret. From now on it is their concern too. They wanted Rita married to the boy she loves, Dilip. It turns out that Dilip's father is a very greedy. So Sherkhan portrays as a millionaire who is deaf and dumb and Bahadur , his secretary. Dilip's father is very glad to meet the millionaire and says he cannot dare break the hearts of two young people in love, specially when he stands to gain a few milions in the process. The result is that the marriage is fixed to take place in on the 15th August when everyone will be free from the worries of responsibility. Rita and Dilip are too happy. Only person who is not aware of all these development is Mem-Didi as she is too sick to leave the bed. But right on the wedding day, Mem-Didi finds out about the wedding. Mem-Didi manages to reach the pandal and insists on telling Dilip's father the gospel truth. This gives a rude shock to Sherkhan and the result of it is that he starts speaking again. But he speaks a bit too loud so that Dilip's father cannot help hearing what he says. Dilips father rushes to the police for this is what he calls an emergency. The marriage ceremony is threatened to come to a premature stop. But then Bahadur and Sherkhan are in charge.
