Day of the Dead (1985) (Blu-ray + DVD)

A Night of living terror led to a Dawn of false hope, but nothing before will prepare you for the darkest Day the world has known!
Below ground in a fortified installation, scientists conduct experiments to understand the virus that has turned humanity into flesh-hungry zombies. Isolated and deprived of natural light, the researchers begin clashing with their military protectors and it soon becomes apparent that their co-dwellers are just as dangerous and unpredictable as the zombies gathering to enter their safe haven... Director George A. Romero follows Night of the Living Dead and Dawn of the Dead with this stark, unflinching sequel that stands as the series' most gritty and astoundingly gory instalment.
