After a mess, gangster Dennis suddenly became the nurse of stroke patient Raymond. He only wanted to break into Raymond's house to pay off some swindlers' debts. Now he, on the contrary, is imprisoned in the house of rich businessman Raymond. Raymond was confined to a wheelchair because of his stroke. At the same time, Raymond's granddaughter Charlotte went to look after him and ran into Dennis in the house, which undoubtedly upset Dennis's plans. However, fleeing is by no means a good option, as the area is being ravaged by snowstorms. Therefore, Dennis must continue to play the role of caretaker. In contrast to Charlotte, Raymond had already seen through Dennis. At this point, a cat-and-mouse game of "using local materials" is carried out between the elderly who are unable to move and the smart young people.
