Two friends, Mireček and Vilém, make a living growing weed and receive an offer they can't refuse: to sell their entire stock of weed in one night. But when they close the deal with a dangerous Bulgarian and his right-hand man, they discover that someone has robbed their grow house. They have a few hours to save not only the deal of the year, but also their own little fingers.

Soulmates Eric and Shelly are brutally murdered when the demons of her dark past catch up with them. Given the chance to save his true love by sacrificing himself, Eric sets out to seek merciless revenge on their killers, traversing the worlds of the living and the dead to put the wrong things right.

Veronika and Mirek try to revive their relationship with a horror-themed Valentine’s trip to the Slavkov Forest, known as the “Knot of Evil.” The tour group includes anxious guide Alex; Ludmila, a detective novel fan sent by her kids; Honza, an extroverted gay journalist seeking a big story; and David and Dana, a married couple who reflect what Veronika and Mirek fear becoming. The bus visits historic massacre sites that seem unimpressive at first, but after Veronika discovers a strange doll, eerie changes unfold. Tensions rise as the travelers’ darker sides emerge—fear, aggression, and suspicion lead to growing hostility. A haunting cry echoes through the woods, suggesting the presence of a mythical being tied to the Slavic legend of the Navka, a spirit from the realm of the dead.
