Watch theEchoes Trailer

Netflix released the trailer ofEchoeson July 09, 2025, and in less than a two-minute clip, it wraps up the plot. The trailer features Monaghan as the twins, Leni and Gina, who seem to have an arrangement with each other and their devilish scheme falls apart when Leni goes missing. The shadowy plot gets more complex with discoveries of dead bodies, including that of a horse, followed by threatening messages that Gina receives.

The overall feel of the series seems quiteeerie and intense, very much like Monaghan’s earlier thriller series,True Detective. The ominous music and gloomy backdrop set the perfect tone for the mystery that forms the premise. Based on the trailer, it’s clear that fans are going to be in for a suspenseful mystery thriller, which, although a little slow-burn, would be quite gripping. There are a few chilling moments as well and the story could graduate from a murder mystery to an unnerving horror in a matter of minutes.

Michelle Monaghan

We are also introduced to the other leading characters, like Bomer’s Jack Beck, Leni’s husband who takes it on himself to find his missing wife with the help of the local sheriff and other authorities. The actors also look poised to deliver a chilling performance, as it’s clear from the trailer. Both Bomer and Monaghan have given us a taste of their horror-thriller performances earlier in theAmerican Horror StoryseriesandEvery Breath You Take, respectively. So we’re hoping their roles inEchoesare going to be equally brilliant.

What Is the Story of Echoes About?

Echoesfollows two identical twin sisters, Leni and Gina with a dangerous secret. They have swapped their lives since they were kids and ended up leading double lives as adults. It’s like the perfect trick, which probably started out as simple fun when they were children, but they never got caught and so no one has ever found out. Their plans, however, have never caused a problem in their lives, and their charades kept everyone else in the dark, even their husbands. It has all been working well for them so far until Leni goes missing. This is where things get all awry and Gina’s life gets thrown into a tailspin.

The secret they never shared with anyone else appears to have gotten out of the bag and out of hand when Gina receives strange and very threatening messages. She soon starts digging deeper into her sister’s disappearance, which could possibly be murder. Her life becomes chaotic and disturbing, and the more she tries to discover, the more unsettling it gets.

With dead bodies, dead animals, and suspicious people, all hell breaks loose for Gina, and questions keep piling up. Did Leni run away, or did she get killed? Or is Leni seeking some kind of revenge on Gina? Who else knows about their secret, and what are they going to do to Gina? And what is Gina ready to do to keep her lifelong secret from being uncovered? You’ll know all the answers to those questions once you catch the Netflix miniseries on August 19.
