Leshka can’t see the summer holidays like his ears! It's necessary to break a leg by falling out of the blue! Now he will definitely spend the whole summer at home with his leg in a cast... But it seems to the boy that his forced confinement is not accidental - someone deliberately confined him to his bed. And then there’s this photo... When Leshka looks at his photo, taken exactly on the day when he broke his leg, for some reason he thinks: his days are numbered... Leshka doesn’t like this photo. And I didn’t like the photographer himself either. This black gentleman smelled of grave cold... But Leshka is not the only one forced to sit at home. All his classmates, who received the photograph of the mysterious photographer, are also sick and slowly fading away...
