Idiot is an ode to all the social misfits and rebels who question dysfunctional man-made norms of society, all the wanderers embarked on the journey of self-discovery and searching for the greater purpose of existence.

A group of friends are led by circumstances to find themselves at the crossroads of fate.

It explores the tale of two girls, Shiza (Komal Meer) and Mishal (Sabeena Farooq), who are childhood friends and share a sisterly bond. Due to their love for one another, Mishal asks her parents to arrange their marriages within the same family so they can live in the same house. Eventually, they become sisters-in-law when Shiza marries Harris, Mishal's older brother, with whom she has been in love since childhood. Mishal feels betrayed when they keep their relationship a secret, but she soon accepts the situation. Later, she meets a handsome young man named Arsal, who initially takes a liking to Shiza but refrains from acting on it because of the girls’ sisterly bond, as his marriage has already been arranged to Mishal. He marries Mishal happily and cares for her. However, things become more complicated for Shiza when her husband dies in a car accident. She is then forced to marry Mishal's husband and live her life as a co-wife. What will be the fate of the three of them?
