Debbie Galardi recalls playing Ouija with her best friend Laine Morris as children. In present day, Debbie throws her Ouija board into the fire, burning it. Debbie implies to Laine that something strange happened with the Ouija board. After Laine leaves, the Ouija board reappears in Debbie’s bedroom. Debbie becomes possessed and hangs herself with Christmas lights inside her home.
Laine attends Debbie’s wake with her boyfriend Trevor, younger sister Sarah, friend Isabelle, and Debbie’s boyfriend Pete. The five friends meet at Debbie’s house and use her Ouija board to try communicating with her. Strange things happen, and a presence smashes Pete’s hand and face into a mirror. Later, the friends start finding the phrase “hi friend” (a message communicated during the Ouija board session) written in different places, like Isabelle’s car window, a tunnel wall, Pete’s desk, and Laine’s computer. Thinking Deb is trying to communicate with them, the group has another Ouija session. They then discover that they are actually in contact not with Debbie but with a spirit calling itself “DZ.” Laine sees the image of a little girl with her mouth sewn shut. The girl warns them to run because her mother is coming. Laine sees an old woman, and everyone flees. Laine later learns that Deb found the Ouija board in her attic and played alone.
