If You Have to Watch 1 Netflix Mystery Show in September 2025, Stream This 1 Right Now

Mixed in among the huge Netflix hits like Wednesday and Stranger Things, there are always a few series that go unnoticed and underrated.

One such series is the French YA mystery-drama The 7 Lives of Léa, which is one of those “everyone who actually watches it loves it but not enough people are watching it” situations.

Watch With Us just got aboard the Léa train, and we’re recommending you check out this Netflix series in September 2025.

Read on to learn why we’re obsessed with this underrated gem.

The Premise Is Irresistibly Unique

The 7 Lives of Léa, based on the novel The 7 Lives of Léo by Nataël Trapp, begins like a lot of teen dramas — a disaffected teenager, Léa (played by Raïka Hazanavicius), struggles to find her place at a party full of other disaffected teens. But things take a wild turn when she stumbles upon a 30-year-old skeleton. After reporting the disturbing discovery, she goes to sleep — only to wake up in the body of Ismaël (played by Khalil Ben Gharbia) — 30 years in the past.

It’s soon revealed that Ismaël is the person whose remains Léa found (in 2021). But traveling into his body is only the beginning of Léa’s bizarre adventure.

‘The 7 Lives of Léa’ Is a Unique Take on Body-Swapping and Time Travel

The mechanics of Léa’s time travel experience are what give the series its name, as it’s quite different from your typical Freaky Friday or Face/Off body-swapping situation. For seven days, Léa falls asleep in 2021 (as herself) and “wakes up” in a different body in 1991 — living out their stories by night.

Soon, Léa realizes her own parents might have been involved in Ismaël’s murder. In the future, she investigates and tries to find out anything she can about the mysterious, unsolved case — and in 1991, she tries to prevent it from happening. It’s a timeline-hopping, mysterious series that fits together like perfect puzzle pieces.

It’s a Delightful ‘90s Time Capsule

As a fun bonus for millennials, this show is a picture-perfect comparison of ‘90s teen culture to that of the present day. The fashion, music and technology that Léa encounters on each of her time travel journeys are wonderfully period accurate, albeit with a French backdrop.

It’s a Rare Miniseries with a Perfect Ending

Without spoiling anything, we’ll just say that The 7 Lives of Léa features a perfect balance of questions and answers, telling a complete story that completely captivates you in its seven episodes. It will leave you wanting more, but not because the story feels incomplete — only because it’s told so perfectly.
