Parents have always warned their children to be careful with strangers. That warning must have slipped Lucy Hale's and Tyler Posey's characters' minds when they, alongside their friends, went to a deserted place to play Truth or Dare, an upcoming movie's namesake.

In the trailer for the upcoming horror film, Hale and Posey play the roles of teenagers having the time of their lives during their Mexico trip. After being invited by a stranger to what looks like an abandoned warehouse, things start to get a little out of hand when the game of Truth or Dare they and their friends are supposed to be playing, gets literally real.

After the stranger tells Hale's character that the Truth or Dare game they are playing is indeed real, strange things began happening. Someone or something begins controlling the players, following them back to America. This mysterious entity then starts to punish those who tell lies as well as those who refuse the dares.

As if the concept of the movie is not creepy enough, the cast seemed to have practiced their disturbing smiles whenever the entity controls their bodies. Their creepy smiles alone make the trailer frightening enough to leave one's nightlights on at night.

Aside from the creepy smiles the cast seemed to have perfected, horror movie fanatics should also look out for the gruesome consequences the players have to face if they fail to comply with the golden rules of the game: tell the truth and do the dare. By the end of trailer, the players are down by half and the dares start becoming more and more life threatening and the quest for truths more demanding.

Hale and Posey will be starring alongside Violett Beane, Hayden Szeto, Landon Liboiron, Sophia Taylor Ali, and Nolan Gerard Funk. The upcoming horror movie will be directed by Jeff Wadlow.

"Truth or Dare" is set to be released on April 13, two weeks earlier than the initial plan of the April 27.
