What happens when five high school students enter detention — but only four make it out alive?

In the upcoming series “One of Us Is Lying,” everyone is a suspect and everyone has something to hide, Peacock said in a statement announcing the casting of "Sing Street" star Mark McKenna.

The series is based on Karen M. McManus’s New York Times bestselling novel of the same name. In the book, the mystery unfolds from the perspectives of all four teenage suspects.

In the series, McKenna will star as Simon, who Peacock said is “a brainy outcast and the creator of a gossip app that holds the entire school captive.”

The posts on his app are “juicy, snarky, cruel, and most importantly: always true,” according to Peacock. “He takes pride in exposing his classmates as the ‘liars and hypocrites they really are.’ Even though all of his classmates read his app, they also all hate him for it.”

Hated or not, he still sets out to solve the school's murder mystery.

For “One of Us is Lying,” Wayne will be acting alongside Marianly Tejada, Cooper van GrootelAnnalisa Cochrane Chibuikem Uche, Jessica McLeod, Barrett Carnahan, and Melissa Collazo.

“One of Us Is Lying” has been described as a mix of the 1980s teen movie classic “The Breakfast Club” and the more recent television series “Pretty Little Liars,” E! Online reported.

The series is being produced by UCP, a division of Universal Studio Group. Darío Madrona (co-creator of “Elite”) is the showrunner and executive producer.

While a release date hasn’t been set, Peacock promises the series is coming soon.
