Nadia, a chef with thirty years of experience, runs a cozy dining room next to the police station. Her son, Pasha, works as an operative and helps his mother with business — police officers often come to her for a bite of homemade food. One day, the police find out that an influential businessman is looking for a new personal chef — and this is a chance to get as close to him as possible. To help her son and his colleagues solve the case, Nadia decides to infiltrate the suspect's house, disguised as a cook, and find herself in the very center of events.
