"Amal kar na rakh phal ki tu arzoo
Tere farz mein hai teri Aabroo......"
Barrister P.K. Anand (Ashok Kumar) was a staunch believer in the highest integrity of character and principles, and believed in duty above all else. He practised in Srinagar and God had blessed him with all that could be desired for a happy life. He had his affectionate wife Tilotama (Nirupa Roy) his only younger brother Manish (Deepak Kumar) highly devoted to him and a very faithful friend Shekhar (Rehman) who lived in Jammu.
When Dr. Manish returned from abroad he met and fell in love with a charming college girl Nina (Vimi). They pledged eternal love to each other. Colleges closed and during the holidays Nina went to Jammu to visit her elder sister Sharda (Leela Naidu), who happened to be Shekhar's wife. At Shekhar's home, all was not well. Sharda, whom he loved dearly, was childless and Shekhar's uncle (Jeevan), who knew the weakness of Shekhar's mother (Lalita Pawar) for a grandson, played upon this as ruse to further his own ends. He introduced Shanta (Shashikala) into the household and began playing upon his old sister's mind to have Shekhar remarried.
Events take an unexpected turn when Sharda dies mysteriously and on her deathbed, places her husband's hand in Nina's. Bound by tradition and honour, Nina had to marry Shekhar.
Sublimely unaware of this, and longing only to meet his sweetheart again, Dr. Manish went gladly on a transfer to Jammu as a Doctor at the City Hospital there. Barrister Anand had asked Shekhar to put up Manish at his home.
When Dr. Manish arrived at Shekhar's house he was stunned to find Nina - but already married. He was heartbroken, but he pledged that because "Greater than a Man's Love is a Woman's Aabroo" he would even die for it.
And then, while under Dr. Manish's treatment, Shekhar died! What had happened? Had Dr. Manish murdered Shakhar, as charged by his own brother P.K. Anand by now become Public Prosecutor, to conduct the case to vindicate justice for his deceased friend against his own brother, and demand the death penalty? Did Dr. Manish get the death penalty as demanded by his own brother? Was his love so impure that he could murder his brother's dearest friend for it?
See "AABROO" for answer.
