Граница миров - All Seasons

After meeting a vampire, the Shilov brothers discover their superpowers. Seryoga and Lyokha learn that the city's research institute houses a portal between the worlds of humans and evil spirits, who occasionally visit. The secret organization "Border of Worlds," led by Pavel Nikitich, oversees the werewolves, witches, mermaids, and other "tourists" from the Dark World. The team includes the "brain" of the organization, Lyudmila Nikolaevna, her daughter Sveta, and the striking vampire Ilona. The Shilovs become part of an unusual team, where they not only have to monitor the "dark" ones, but also collect fragments of a powerful artifact.
 

The second season begins a year and a half after the ancient vampire Vladislav possessed the head of the Dark Interpol, Andron, and almost destroyed all life. Now, the employees of the secret service "Border of the Worlds" face more serious challenges and embark on a major investigation as an unknown creature crosses the border, hypnotizing everyone in its path. Personal issues also add to the difficulties, as Lyudmila Nikolaevna suddenly receives a new body, and Lyokha undergoes an unusual transformation and encounters a vampire who wants to steal him away from Ilona.
