Severed
Severed (2005), also known as Severed: Forest of the Dead, is a Canadian horror film that combines environmental activism with zombie horror. The story unfolds in a remote logging area where a corporation's genetic experiments to accelerate tree growth inadvertently lead to a viral outbreak. When a logger is injured by a spiked tree, he becomes infected and transforms into a zombie, triggering a cascade of infections among both loggers and environmental protesters. As the virus spreads, the survivors—comprising corporate personnel, loggers, and activists—must navigate their differences and the dense forest to escape the growing horde of the undead.
