The content of the movie can be summed up in one sentence: a colleague pretends to use the excuse of rain to test his friend's wife, and the conclusion is - never underestimate your husband's best friend. After taking his best friend home because he was too drunk, he realizes that his friend's wife is a woman who is not only beautiful and charming but also extremely seductive. Even though she is his best friend's wife, from the moment they met, he has harbored plans and desires to possess her because she is the ideal woman model in his life. Finally, fate grants him an opportunity when, on a night of heavy rain, his best friend has to work late, which is indeed a perfect chance for the dark plans about to unfold. With heavy rain, using the excuse of coming home late due to bad weather, he knocked on her door to ask for shelter until it stopped. Because she is the wife of her husband, she did not hesitate and immediately agreed - this is the key point that leads to an affair occurring on a cold winter night with extremely cunning schemes.
