Ivan Sviridov returns from the army and meets with childhood friends Ravil, Markin, Pashula and Ritka. Friends arrange a party for him, at which Ivan meets Mira. The comrades offer Ivan to work with them in an auto repair shop, but Ivan has more ambitious plans: he wants to finish developing a unique technology, which he wrote about in his diploma a year ago and which immediately attracted the attention of serious businessmen. However, Uncle Misha has prepared his own plan for his nephew, in which his entire future career has already been thought out for Ivan.
