Maryana and the calico cat Felka have an ordinary life with a lot of problems: their mother is seriously ill, her brother got into a dark situation, there is barely enough money for everyone. By the way, an old acquaintance offers Maryana to make good money by looking after his apartment. The girl, of course, agrees - she needs money. And the guy is very attractive! Ivan Raikovsky is Maryana’s first and, perhaps, only love. While Felka charms all the residents of the new apartment, and Maryana arranges the life of the Raikovskys, Ivan, concerned about the girl’s situation, tries to figure out how it happened that the fragile Maryana remained in her family as the eldest? Maybe her relatives are hiding something? Or maybe he himself has a secret from Maryana?..
