The 15-year-old Oscar (Alan Stanford) is precocious and considerate. He speaks fluent French and reads Voltaire frequently. All the girls of his age love him, but he only likes "old woman". This holiday, he is about to take the first step of "turning an adult" to tempt the woman he loves to hook up, which is none other than his little mother, Eve (Chevrolet Weaver). However, the sky does not follow the wishes of the people, Oscar has not yet caught Eve, but first to a group of elderly sex girls, Eve's sister Taodian. Oscar, 15, is smart and studious. Dissatisfied with the shallowness of girls of his age, he fell in love with a mature and learned woman, his stepmother, Eve, which his professor father knew nothing about. He wanted to confess his love to his stepmother on Thanksgiving night, but it was difficult to open his mouth. He slept drunkenly with his stepmother's close friend Diane and lost his virginity. Father's loving care, Diane's entanglement and Oscar's pure love for his stepmother constitute the comedy elements of this film. The plot is absurd, but as Diane said to Eve in the movie: do you remember how we dreamed when we were 15?
