Three best friends and dedicated roleplayers take to the woods to reenact a dungeons and dragons-like scenario as a live action role-playing game. Trouble arises when a prop spellbook purchased from the internet ends up being a genuine grimoire and they unwittingly conjure up a blood-lusting succubus from hell.

The film follows Mr. Shi, a retired widower from Beijing. When his only daughter, Yilan, who lives in Spokane, Washington and works as a librarian, gets divorced, he decides to visit her to help her heal. However, Yilan is not interested. She tries keeping an emotional distance but when this finally fails she begins physically avoiding her father. He confronts her about an affair with a married Russian man and she, in turn, lets loose about all the gossip she'd heard as a young girl about his alleged affair with a female colleague back in China.

A private detective is hired to find a missing stripper but the job turns complicated when everyone he questions ends up dead. From the mean streets of Los Angeles to the desolate desert of New Mexico, Cruz must contend with a brutal Russian Boxer, three brash LAPD detectives, an aged billionaire looking for the Big Bang, and the billionaire's stunningly gorgeous wife. The solution to the mystery will cost ten lives, net $30 million and just might explain - well - everything.
