A zombie charges at survivors in the "Survival Zombie" competition in Collado Villalba, outside Madrid. According to the back-story of the "Survival Zombie" contest, participants, who signed up as survivors, are trapped for a night in a city that has been infected with a virus that causes humans to turn into zombies.
The objective of the game is for the survivors to stay alive until morning by avoiding getting touched by a zombie. In order to do so, the contestants need to find clues that will help them reach a safe haven, the end point of the contest. Survivors are not allowed to attack the zombies, a role made up of other players as well as members of the contest organization, so their only means of survival is by avoiding them.
A single touch of a zombie eliminates the player, but they can return as zombies after getting made up, so that they can continue playing. A group of actors dressed as soldiers are also involved in the game, helping some players against the zombies or making it harder for others to solve the clues to survive.
