Night Of The Living Dead (1968)

A group of strangers ends up trapped in a rural farmhouse while the dead start coming back to life and attacking the living. It starts with a brother and sister visiting a graveyard when something strange happens, forcing the sister to flee to the house. Others soon show up, including a calm but decisive man who takes charge as the group tries to figure out what's going on and how to stay alive. Tension builds not just from the undead outside but also from arguments and mistrust inside. News reports slowly reveal that this outbreak is widespread, with no clear cause or solution. As night falls, the attacks intensify, and the group's efforts to barricade and defend the house grow more desperate. The ending hits hard, offering no easy answers and leaving a bleak but memorable final note.
