"Sleepy Hollow" is set to air its next episode titled, "Loco Parentis." Based the trailer, a young girl has welcomed a demon in her house, prompting the entire team to investigate the case.

Next week will be exciting for all avid viewers of "Sleepy Hollow." The team, including Diana and Ichabod, will be faced with a new case that involves a young girl that has a demon inside her home. Diana, on the other hand, has to face the return of her ex-lover, and decide if he is ready to be the father of her child.

"Just before Molly's 11th birthday, her father returns from duty. As Diana begins to wonder if her ex might be ready to be a part of his daughter's life full-time, the team has a shocking realization in the all-new 'Loco Parentis' episode of 'Sleepy Hollow,'" the synopsis reads.

The realization, according to several entertainment news sites, is all about Diana's daughter, Molly, who was gone missing. The promo video shows Diana worried about where Molly has gone while Ichabod tries to search for her.

The scene shifts to the Homeland Security agents asking Ichabod about how a demon can locate the young girl. He then shows Molly's drawing book where she mysteriously drew occult symbols.

Diana said, "She went looking for answers on her own." Ichabod then adds, "And in doing so she might have found a flair into the darkness."

"Sleepy Hollow" follows the story of Ichabod Crane, played by Tom Mison, as he defeats supernatural evil forces that are plaguing the town of Sleepy Hollow. The last season changed a lot about Crane's story following the death of his partner and co-Witness, Abbie Mills. He is now situated in a new city with new allies to work with, as he embarks on to save the nation from demonic threats.

The 7^th episode of "Sleepy Hollow" season 4 airs on Friday, Feb. 17, at 9:00 p.m. EST on Fox.
