District prosecutor Margaret finds herself in a very delicate situation: she is in a room of an elite hotel, her clothes are covered in blood, and there is a dead body of a young man in the bedroom, whom she met earlier in the evening. Frantically flipping through the numbers in her phone book, Margaret finds the contact of a person who "solves problems." Soon, a professional cleaner appears, who immediately gets to work. However, a moment later, another problem solver enters the room, summoned by the hotel owner. Now, these two seasoned specialists, who are used to working alone, will have to work together, overcoming their mutual dislike.
