Pallavi, an air hostess by profession, is a vivacious and venomous as hell girl, who lives her life out loud and on the edge. She lives by just one rule: fuck and forget. The one side that nobody knows about her is that she still hasn't moved on from the hurt of her first love: Haasil. Haasil is a successful, self-made and young entrepreneur who is both physically and emotionally recuperating from a fatal accident in which he lost the true love of his life. Swadha is a corporate girl, who is cute, unintentionally funny and head over heels in love with Haasil. That Kiss in the Rain happens when Pallavi, Haasil and Swadha are touched by the sublime power of love in different ways, till their paths cross and their destinies collide, bringing them at a crossroad where each has to make a life-altering decision.
