The Murder Club is back in the new trailer for One Of Us Is Lying season 2. Based on the 2017 novel of the same name by Karen M. McManus, One Of Us Is Lying debuted on Peacock last October. The series follows five teens who enter detention, much like in the style of the classic high school comedy The Breakclub Club, but all of that changes when one of them dies under mysterious circumstances and an investigation ensues. The ordeal also forces the group to be more honest about the secrets they've been keeping, leading to mistrust and broken relationships in the process.

The adaptation premiered to largely positive reviews, with particular praise being given to the show's forward momentum and its ability to surprise. This was particularly evident in the finale of One Of Us Is Lying season 1, which sees the main four characters — Addy (Annalisa Cochrane), Cooper (Chibuikem Uche), Bronwyn (Marianly Tejada), and Nate (Cooper van Grootel) — vowing to keep another deadly secret. But, with enough time, it becomes clear that they're being blackmailed by an unknown source that's known only as 'Simon Says'.

Peacock has released a trailer for One Of Us Is Lying season 2, which debuts all eight episodes on October 20, picks up right on that thread. Although the group, known affectionately as The Murder Club, tries to move on with their lives, Simon is quick to remind them of what they did. In the trailer, which you can see below, the foursome quickly runs into trouble when they attempt to unmask their blackmailer.

What To Expect From One Of Us Is Lying Season 2

Picking up after the shocking death of Jake Riordan (Barrett Carnahan) and the group getting blackmailed as a result, One Of Us Is Lying season 2 promises to keep the thrills coming. According to showrunner Erica Saleh, the show's protagonists will continue to have to reckon with who they really are all while being emotionally tortured by Simon Says. As seen in the trailer, even though they have their own romantic and familial dilemmas to juggle, the games being played by the mysterious Simon look to become all-consuming and even potentially life-threatening.

All the episodes debuting at the same time could benefit the show. Although there are many flaws to that sort of release model, it actually helps a twisty and propulsive series like Peacock's adaptation. Viewers can take it in during a few sittings, savoring every unexpected twist rather than having to wait a week between reveals. And as the streaming service looks for a big hit, positive word-of-mouth could help solidify the future of One Of Us Is Lying.
