Sunita, rich and only daughter of a well-known barrister; Kamal, a poor boy with high ambitions. Both students of the same college. Love knows no barriers, economic or otherwise, and Sunita and Kamal are devotedly in love with each other. A case of the path of love being smooth. Their respective parents readily agree, and their affair culminates in a happy marriage.
His engineering degree enables Kamal to secure an excellent position in a big firm with the influence of his close friend, Mohan, a senior executive in the concern. Kamal and Sunita are installed in the Company’s residential quarters, allotted to them with Mohan’s help. They prepare to settle down to a life of eternal bliss; their love is supreme, unparallel. Neighbour Mohan is a devoted friend, in fact the perfect human being yet leading an unhappy life due to his having a nagging and unstable wife. Mohan has philosophically accepted his lot, and never expresses his pain to anyone. He drowns his sorrows by playing haunting melodies on his favourite sitar.
Kamal and Sunita plunge into the pleasure of marital life. Their love is so deep, their affection so intense that a third factor gets an opportunity of making an unwelcome intrusion. When love is blind, jealousy is often unmanageable and, to the victims quite unbearable.
Is Kamal the victim? Or a man with a fanciful imagination? Is Sunita wronged? Or is she the wrong doer? Is Mohan the third part of an unfortunate triangle? Or the innocent victim of a fouly suspicious mind?
This, then, is “Aap Ki Kasam”. The story of love. Of jealousy. Of man’s failings and his heart-rending repentance. The drama unfolds and the truth dawns that it is but natural to be possessive in love, whilst suspicions can only bring disaster in their wake. Once the dragon of doubts creep in, it may only spell ruin. This is “Aap Ki Kasam”. The daringly different motion picture on the most burning of all problems that beset lovers, wives and husbands.
