An experimental bioweapon, developed by the U.S. government, goes disastrously wrong and turns the population of a small Eastern European town into bloodthirsty zombies. In an attempt to contain the outbreak and cover up the accident, a team of mercenaries is dispatched. Their mission is to detonate a nuclear bomb in the town to eradicate the zombies and any evidence of the government's involvement. The team is led by a grizzled war veteran with a troubled past, who reluctantly accepts the mission due to its high stakes and lucrative reward. They venture into the infested area, armed to the teeth but quickly realize that their weaponry might not be enough against the overwhelming horde of undead.

As the mercenaries make their way through the devastated town, they encounter various survivors and gruesome scenes of destruction. Tensions mount within the team as they face constant waves of zombie attacks and internal conflicts arise. Trust issues and personal agendas threaten to derail their mission. With time running out and the stakes getting higher, the team must navigate through the chaos, struggling to reach their objective while survival becomes increasingly uncertain.
