One of Us Is Lying

Five high school students walk into detention after a routine day and only four walk out alive. The mystery that follows threads through the halls as each teen becomes a suspect and every secret feels like a clue. Addy, Bronwyn, Cooper, Nate, and Janae are drawn into a web of motives, lies, and half truths that forces them to confront what they’re willing to hide to protect themselves and the ones they care about. The series tracks their efforts to piece together the events, while outsiders try to reconstruct the story from rumors, social media posts, and the versions people want to believe. With danger looming, trust becomes the most fragile element of all.

Premiering on Peacock in 2021, One of Us Is Lying was created for television by Erica Saleh and adapted from Karen M. McManus's bestselling novel. The ensemble ride features Annalisa Cochrane, Marianly Tejada, Chibuik Uche, Cooper van Grootel and Jess McLeod.

Fans of the source book leaned into the series as a contemporary teen mystery that leans on social media as a narrative engine. The show sparked online discussions around character motives and updated the classic whodunit for a digital era. Its character work and brisk episodes invite repeat viewing.

Critics praised the tight pacing and the way the cast carries a dialogue driven plot with tension that lingers between each episode. The show probes themes of truth versus image, loyalty, and how peer pressure distorts memory, while keeping the focus on four teens whose reputations hang in the balance.
