Truth or Dare

Olivia, Lucas and a group of their college friends travel to Mexico for one last getaway before graduation. While there, a stranger convinces one of the students to play a seemingly harmless game of truth or dare with the others. Once the game starts, it awakens something evil -- a demon which forces the friends to share dark secrets and confront their deepest fears. The rules are simple but wicked -- tell the truth or die, do the dare or die, and if you stop playing, you die.

Plot
Olivia Barron is a college senior who is seen by others as a good girl who always puts others' needs before her own. During her last spring break, although she initially plans to build houses with Habitat for Humanity, her best friend Markie convinces her to come to Mexico with their friends instead. At a bar, Olivia meets a man named Carter who invites them to go drinking at an abandoned church. There, Carter suggests they play truth or dare. During the game, their friend Tyson reveals that Olivia has a secret crush on Lucas, Markie's boyfriend, which she denies. Carter admits that he tricked them into playing a supernatural version of the game and warns them to do whatever the game asks or they will be killed.

Back at school, Olivia sees hallucinations calling on her to pick truth or dare. She picks "truth" and blurts out that Markie has been serially unfaithful to Lucas. The friends learn that Ronnie, another friend, was forced to kill himself after failing to complete a dare. Lucas picks "truth" and admits that he has always had feelings for Olivia. Markie is forced to break Olivia's hand while their closeted friend Brad is forced to admit to his father that he is gay.

Disbelieving the reality of the game, Tyson denies his turn and is killed. The group discovers a story online about a woman named Giselle who lit a woman on fire in Mexico while playing truth or dare. They arrange a meeting with her through social media. Giselle reveals that her friends were playing the game in that same church. One friend, Sam, got drunk and began trashing the place. When they got home, the game somehow continued and only she and Carter survived. Carter was dared to involve more players in the game to give themselves more time before it became their turn again. Giselle reveals that she has been dared to kill Olivia and tries to shoot her, but her friend Penelope dives in front and is killed instead. Having failed her dare, Giselle is forced to kill herself.

Olivia is dared to sleep with Lucas. While they have sex, Lucas is forced to admit that while he cares about her, he is still in love with Markie. Olivia and Lucas drive to Tijuana and meet Inez, a former nun at the church who cannot speak. By writing on paper, Inez tells them how she summoned an ancient demon named Calux who possessed the game of Truth or Dare to save herself from a sadistic priest. However, Calux kept the game going and killed all her friends. She trapped Calux with a ritual involving cutting off her tongue and sealing it in a pot. The group realize Sam must have broken the pot and released Calux, and to trap him, they need to find Sam.

Brad is dared to threaten his father with a gun. As he does so, he is shot and killed by an approaching officer. Olivia learns that Carter and Sam are the same person. She is dared to speak the truth and tells Markie that the night Markie's father killed himself, he had sexually assaulted Olivia and she had told him that Markie would be better off if he was dead. Though at first angry and hurt, Markie, after contemplating suicide with her father's handgun, forgives her friend, and tells her it is not her fault as her father had tried to kill himself before.

Olivia, Markie, and Lucas find Sam and force him back to the ruins of the church. As Sam goes through the ritual to trap Calux, Lucas is dared to kill either Olivia or Markie. When he refuses, Calux possesses him and forces him to kill himself after killing Sam so Sam cannot complete the ritual. When Markie's turn comes, Olivia tells her to choose dare, then refuse to complete it. Calux possesses Markie, at which point Olivia forces Calux into the game by asking him to pick truth or dare. The demon is forced to tell the truth that there is no way they can make it out of the game alive because Sam is dead. They'll die unless they add more people to delay their next turn.

Olivia uploads a YouTube video, in which she briefly warns viewers about the game and its rules. She then asks "Truth or Dare", involving whoever hears the phrase into the game, delaying her and Markie's next turn for the time being.
