The Body (2018) on Netflix

Plot summary

Wilkes is a sophisticated hitman who has just killed a famous man in a lavish apartment and told his employer the job is done. What remains is the body, wrapped like a mummy and dragged through the hotel lobby into the street, where people take the bundle for part of a Halloween costume. He meets Alan, Dorothy and Nick, three young people headed to a party who think his costume is cool and ask him to join them. He accepts to get a ride away from police investigating vandalism of parked cars.
