The film is adapted from a real event. The breakdown of the family caused James (Luke Treadaway) to suffer a huge blow and began to abandon himself. He became addicted to drugs, penniless, and became a street performer. Val (Joanne Froggatt) is the drug rehabilitation doctor in charge of James. With her help, James finally has a home that can shelter from the wind and rain. Val firmly believes that James can completely get rid of the temptation of drugs by his own will. One day, a stray cat broke into James's home. James adopted it and named it Bob. When James left home and went to the streets to perform, Bob followed him closely. Soon, the combination of one person and one cat attracted the attention of passers-by, and James's economic situation was greatly improved. At the same time, James met Bella (Ruta Gedmintas), a woman who lived next door, and James rekindled his desire for love in Bella's body.
