Какая у вас улыбка (1974)

Sergey Savinov, a yesterday's schoolboy, who failed at his entry exams, is at the crossroads. Where to go to work? After working as a stand-by in a local recreation-and-entertainment park, he tries himself as a proof-reader in typography, a laboratory assistant in a plant and exhausts all his stock of photos for passes. To replenish it, he heads for a nearest photo saloon, and makes a conclusion, that his calling, which he long considered as a hobby, is photography. A work which brings so much happiness both to him and to other people.
