Four unfortunate married women who have been suffering from sexual damage in their living environment every day. They, who have no acquaintance with each other and have nothing to do with each other, are drawn to a strange fate on this day and board the same car on the same train at the same time. The powerful misfortune and the aura of Eros released by the four people completely change the air inside the car, transforming the passengers into a vicious group. There is no common sense or morals in this "big train" where chaotic desires and pleasures swirl.
