Two of the Lakewood Six will face the masked Killer on the upcoming finale episode, titled "When a Stranger Calls," of the second season of the American horror series, "Scream."

The 12th and final episode of season 2 is expected to be the most shocking in the season as Emma (Willa Fitzgerald) and Audrey (Bex Taylor-Klaus) decide to do a risky move. As they are about to finally face off the killer, they will also discover Piper's (Amelia Rose Blaire) last surprise.

The promo trailer for "When a Stranger Calls" shows Emma and Audrey meeting with the killer face-to-face. However, they seem trapped to the perpetrator's games. The killer warns them that if they attempt to surrender to the cops or get caught, he will gut someone they love. Then, Keiran (Amadeus Serafini), who is dead worried about Emma, reunites with her.

Noah (John Karna), on the other hand, is able to talk to Emma on the phone and warns that she and Audrey are both going to hit the 10 most wanted territories if they are not careful enough. Noah convinces Sheriff Acosta (Anthony Ruivivar) about his friends' innocence. However, Acosta insists that the evidence points out to them, if they are not the killers, then he wonders who it could be. Noah suggests that the police should look into Eli (Sean Grandillo) since he was in Lakewood last year and was present at Piper's burial, which means that he knows Piper.

The remaining members of the Lakewood Six meet each other to figure out who the real killer is. Noah even thinks that the killer is possibly just one of them and could have enlisted another accomplice.

Meanwhile, the previous episode, titled "Heavenly Creatures," showed Emma and Audrey at the pig farm to recover Emma's "Dream Diary." Then, Mayor Maddox (Bryan Batt) was murdered.

"Scream" season 2 finale airs on Aug. 16, Tuesday, on MTV.
