Nobody knows what's waiting for us around the corner. On the last day of her 13th birthday, following a rabbit into a St. Petersburg gateway by a strange attraction, Alice suddenly finds herself in a mysterious forest. A place where everything is the other way around. To the wild sounds of a piano, which is driven along country roads on a tractor, Alice meets a wild company that, instead of St. Valentine's Day, celebrates the feast of St. Tryphon the Mouser, unable to leave the festive table from winter to summer because of the curse of the Elder, who punished them for "blasphemy." Helping to solve this problem, Alice receives a motorcycle as a gift - both a dream and a means of transportation - and sets off on a journey. Where will it lead her? What awaits her, a lonely and strong girl? And most importantly, why did she tag along with the white rabbit? Who are her parents? And who is she really...

The film traces the path of the hero (formerly an ensign and a Knight of St. George, and then a talented commander of the Red Army) from the Civil War to the Great Patriotic War.
