In this black-and-white biographical drama, we find ourselves in Leningrad at the end of the 1980s, a time when the authorities review and control everything that happens. During this, however, the musical and creative scene among the young Russians and the underground scene is growing. It is during this time that Mike and his wife Natasha meet Viktor. In addition to a love triangle, they will together change the musical landscape of the Soviet Union. In his review on Kulturnytt in P4, Björn Jansson writes, "Leto is a black and white film, with some color scenes, it is a story of some musicians who live in a dictatorship but still find ways to play, spur each other and to love." In Kommunalarbetaren, Elin Steen writes that the film "pays tribute to the longing for freedom and the drive to go your own way."
