In 1965 Los Angeles, a widowed mother and her two daughters add a new stunt to bolster their séance scam business and unwittingly invite authentic evil into their home. When the youngest daughter is overtaken by the merciless spirit, this small family confronts unthinkable fears to save her and send her possessor back to the other side.
The spirit is actually Alice’s teenage daughter Paulina (Annalise Basso), while her younger daughter Doris (Lulu Wilson) was hiding to create the effects of candles blowing out. Alice scolds Lina for scaring Mr. Browning and costing them their pay, but Lina defends her actions because she thinks Jenny was a bitch. Alice agrees.
Lina sneaks out at night to go to her friend Ellie’s (Halle Charlton) house. The two of them, plus Lina’s boyfriend Mikey (Parker Mack) and other friend Betty (Alexis G. Zall) play with a Ouija board game. They try to contact a spirit, which creeps the hell out of Betty. Ellie’s mom bursts through the door, making Betty scream. Alice later picks up Lina, upset with her.
While the girls are at school, Alice goes to find a Ouija board of her own after Lina suggests it could be good for business. At night, Alice uses the board and unknowingly makes contact with a spirit named Marcus, who speaks through Doris. Doris responds to Alice’s questions, to Lina’s confusion.
Doris uses the Ouija board on her own – despite the first rule of the game being not to play alone – in the hopes of making contact with her dead father Roger (Michael Weaver).
At school, Father Tom (Henry Thomas) calls Alice in to review Doris’s homework. It’s all written in cursive, despite no one having knowledge of Doris ever learning how to write like that.
Alice and the girls return home to find a notice of foreclosure on their door. Doris returns with a pouch full of money that she claims Roger told her about. She shows her mom and sister a space in the basement wall that contained the money. Later, Doris shows Alice and Lina how she communicated with Roger. To their astonishment, the planchette moves on its own when Alice asks the spirit where Roger was when she told him she was pregnant with Lina. The planchette moves around to spell “SHOWER”. When Alice asks if Roger is really there, it moves to YES. The girls look through the planchette lens to see if they spot anything, but Lina is too freaked out to keep looking.
