A well-known jeweler in the city made an unusual key for his son in the form of beautiful gold jewelry. With this key, he always locks in something in his deposit safe of the bank something very valuable for him. Fate is unpredictable, so the jeweler dies, his son Sashko goes to prison. With easy submission, Sasha's two unhappy friends, Stas and Bonya, hit 100 pounds of gold. So when Sashko goes free, instead of looking for his father's murderer and having his key stolen, he has to solve his debt problems. However, this is becoming increasingly unrealistic: the key and gold races include the mayor of the city and a couple of strange criminal groups. Owning the key to success does not mean success itself.
