The beginning of the 1990s in newly independent Lithuania. There is chaos in the republic's politics, economy and underworld. The daily lives of the people are largely controlled by criminal groups that feel invincible alongside the helpless government and the fearful citizens. At the center of the first season of the series is one of the most powerful criminal groups in Vilnius, nicknamed the "Pythons", led by the Dadian family.
The series is about a woman who is literally given a second chance at life – this time around she must change her ways and prevent her own murder, which raises bigger questions about whether change is possible or if everything is predetermined.
Meet Mon, a violent killer faithful only to his own eruptive desires, and his timid companion Toshi, a demolition-devil with a fanatical thirst for destruction. Their killing-spree across Japan is destined to intersect the path of the enormous "Higumadon", a mysterious beast on a Godzilla-like rampage from Hokkaido to Tokyo.
