The film, based on a true story, focuses on the aftermath of Indira Gandhi's assassination which occurred on 31 October 1984.

In 24 hours of uncertain oscillations, helplessness, and with their relatives dying and neighbours turning hostile, Devender's family seeks help from their Hindu friends who live across town.

As Pal, Tilak and Yogesh travel to save Devender's family, they come face-to-face with the destruction of humanity.

In their attempt to ferry Devender's family to safety, Pal, Tilak and Yogesh must face their own demons first.
