Nick (Timothée Chalamet) has been a well-behaved boy since he was a child. He has a beautiful and fair appearance, a lively and cheerful personality and a smart brain. In his student days, he easily achieved impressive grades. He applied to six universities and was recognized and admitted. Everyone who knew him believed that this young man had a promising future. However, Nick's fate changed dramatically when he came into contact with something called "marijuana". This drug that could bring him short-term stimulation and hallucinations soon made Nick deeply involved. After that, the unsatisfied Nick turned from marijuana to viruses and became a drug addict. In order to quit drugs, Nick went to a drug rehabilitation center and participated in mutual aid meetings, but these efforts were ultimately in vain.
