In the small seaside town of Yuzhnomorsk, a former resident of these places, young opera Andrey Korablev, is returning from the capital. Andrey has a sad reason for returning to the city of his childhood - he came to bury his only loved one, his grandfather, an old fisherman who recently died at sea. Andrey is remembered in the city. Once he served in the local Ministry of Internal Affairs, he left many friends and acquaintances on both sides of the law. Communicating with them, Andrey comes to the conclusion that the death of his grandfather was not accidental.
