This is an episode where the milieu of Pustak is set, the characters are established. It also focuses on an event where the four main characters have kidnapped a woman and it focuses on the back-story of how the kidnapping happened which constituted the preceding events of four days. It shows the events that took place 4 days before the kidnapping; but it also represents a contradiction that the characters are somewhere driven by the factor of at least one good aspect and one primary good deed of saving a life by the woman.
