Mr X in Bombay

Shobha Mathur lives a wealthy lifestyle with her Professor dad who is now carrying out experiments on various issues One day while doing so he makes an employee named Manohar drink a potion which results in his death Rajan comes to their rescue gets rid of the body and starts blackmailing Mathur which can only end when Shobha marries Rajan Then one day Shobha meets a poet by the name of Sudarshan and both of them fall in love When he asks for her hand in marriage Shobha refuses The next day Shobha finds a note addressed to her from Sudarshan in which he has stated that he is going to kill himself Thereafter every night she starts to hear Sudarshans voice blaming her for his death as his soul is unable to find solace With Sudarshan out of the way Rajan readies himself for marrying Shobha and it looks like he may have his way with the Mathurs after all without having to encounter any more obstacles
