A bus is a place where all kinds of people, men and women of all ages, ride together. A lewd atmosphere hangs over the packed bus. Women are shaken when they see molestation taking place behind them, but for some reason, they end up waiting for it. A married woman seeking excitement in her agonizing daily life, a female college student looking for new pleasure, a schoolgirl yearning for a dangerous experience... She accepts the hand that sneaks up on her, her breath escapes, her underwear stained with love juices. The molestation that spreads contagiously inside the bus knows no bounds.
