Emmy nominee Constance Zimmer returns to Lifetime to executive produce and direct her first feature length TV movie, Boy in the Walls. Zimmer made her directorial debut on Peabody winning and Emmy nominated Lifetime series UnReal.

The original movie will star Ryan Michelle Bathe (End Game, Sylvie's Love), Luke Camilleri (Hemlock Grove) Cassandra Sawtell (Disappearance in Yellowstone) and Jonathan Whitesell (The X-Files). Inspired by actual 'Phrogging' events, of people who discover there is someone secretly living inside their home, Boy in the Walls will debut later this summer on Lifetime.

"We absolutely loved working with Constance when she starred in UnReal and even prouder when she made her directorial debut with us through our Broader Focus initiative and has since continued to direct episodic series for others," said Tanya Lopez, EVP, Scripted Content, Lifetime and LMN. "But we always love a good homecoming and thrilled she now gets to make her TV movie directorial debut for Lifetime too."

"I'm grateful to Lifetime for giving me the opportunity to executive produce and direct my first feature with them. They continue to be incredibly supportive of me, who could ask for anything more?" said Constance Zimmer.

In Boy in the Walls, recently married Alisa Jensen (Ryan Michelle Bathe) has given up her vibrant Manhattan lifestyle for a quiet existence in rural Connecticut but struggling to adjust to her new role as a stepmother to Maya (Cassandra Sawtell) and Theo (Mikkal Karim-Fidler). Hoping this move can be a fresh start, Alisa finds herself cracking under the pressure with her husband Chris (Luke Camilleri) constantly away at work, limited job prospects, and a rebellious Maya to contend with.

But when Alisa begins to hear strange noises in the house, she can't shake the feeling that someone is always watching her. Alisa later makes a terrifying discovery of what is truly within the walls. Jonathan Whitesell stars as Joe, who is secretly watching Alisa and her family.

Boy in the Walls is produced by Lighthouse Pictures for Lifetime. Constance Zimmer, Manu Boyer, Kevin Leeson, Shawn Williamson and Jamie Goehring are executive producers. Zimmer (Big Sky, Good Trouble, House of Cards) also directs from a script written by Katrina Onstad and David Weaver.
