Prosypatsya utrom i obnaruzhivat, chto prozhivaesh dni v obratnom poryadke, - shtuka poserezney "Dnya surka"! Shestiklassnik Gleb Elizarov vsego lish natsarapal na drevney stene datu "23.05.2013" - i otpravilsya s paroy odnoklassnikov snachala v 22 maya, a zatem v 21-e, 20-e, 19-e...

Ekskursiya k arheologicheskoy nahodke, yakoby otnosyascheysya k tsivilizatsii mayya, stala dlya troih rebyat nachalom priklyucheniya, rasskaz o kotorom ne ubedit ni odnogo vzroslogo. Ili vse zhe naydetsya tot, kto im poverit?
