About to get married, a man tells Azu, his tomboyish best friend of ten years, and they decide to take one final camping trip before his wedding. A sudden downpour floods the tent, forcing them to huddle together for warmth. As they heat each other's chilled bodies skin to skin, they become acutely aware of each other as a man and a woman. Though they know it is wrong, they gradually give in and spend the night joining their bodies in an affair.
