My Boyfriend's Wife Is Dead: A Solid Thriller That Bets on Performance Over Plot
My Boyfriend's Wife Is Dead is a Lifetime thriller that premiered June 27, 2025, starring Brianna Cohen as Lena, a woman recovering from divorce who enters a throuple with glamorous couple Iris and Dean — only to have Iris murdered and find herself as the prime suspect. It's 90 minutes. It's worth watching if you like character-driven mysteries more than puzzle-box plotting. The catch? The mystery itself isn't hard to solve.
The setup: Divorce, throuples, and murder
After a bad breakup, Lena does something she never would have before — she accepts an invitation into the intimate lives of Iris and Dean, a couple who seem to have it all figured out. For a while, the arrangement works. She gets excitement, companionship, escape. Then Iris turns up dead, and Lena becomes the obvious target for suspicion: the outsider, the newcomer, the woman with a motive. The film's real tension isn't whether she'll prove her innocence — it's whether the actual killer might be someone she's already trusting with her life.
What's interesting is that the film doesn't just want to play whodunit. There's something underneath about what women do with freedom after a relationship ends, and how quickly that freedom gets weaponized against them by people who decide you're convenient.
Why the mystery falls short (but the film doesn't)
Here's the honest part: if you've watched a handful of cable thrillers, you'll see the ending coming. The script doesn't work very hard to hide its hand. A review at Hotchka nailed this, calling it a "very mixed bag" — and that's fair. The mystery mechanics are thin.
But thin mystery ≠ bad movie.
What keeps you watching is the performances. Brianna Cohen carries the emotional weight across both the early scenes where Lena's cautious and excited, and the later ones where that excitement curdles into genuine fear. Donny Boaz (a steady presence in exactly this kind of cable thriller) brings a particular kind of charm to Dean — the sort that makes you want to trust him even when every instinct says you probably shouldn't. Nicole Marie Johnson, despite playing the murder victim, gets enough screen time to feel like a real person rather than just a plot device waiting to be discovered.
The thing nobody mentions is how much the Florida setting does for the atmosphere. All that bright light and open space should feel safe, but the cinematography keeps using it to make Lena feel exposed. You'd think sunshine would comfort her. Instead it isolates her.

The film was produced by Sunshine Films Florida for Lifetime, and it shows — this doesn't feel rushed. The cinematography has genuine warmth to it. The pacing in the first act, where the throuple dynamic is being established, is more patient than the genre usually allows. For current availability across all platforms, Movie OTT's where-to-watch widget updates in real time as titles move between services.
The scene that actually lands
Midway through the film, there's a moment where Lena finds something in Iris's belongings that reframes everything she thought she knew about the relationship. It's quiet. It's well-played. It's genuinely unsettling — the single best moment in the movie. Cohen and Johnson have a strange, charged quality in their shared scenes that makes Iris's death matter more than it should, given how predictable the mystery becomes.
That scene is why you watch this, honestly. Not to solve the murder. To watch a woman actively refuse to be made into a villain by people who've decided she's convenient.
Who should watch this
If you're a Lifetime regular, My Boyfriend's Wife Is Dead delivers what the network does best: a watchable, well-produced thriller that doesn't overstay its welcome. It's got the production values of something that cost more than it looks like it did. The mystery won't surprise you, but the performances will. It's a solid 90 minutes for anyone who enjoys watching character work happen inside a whodunit's framework.
Don't expect a puzzle box where all the clues line up and you feel smart for catching them. Expect a character study wearing a thriller's clothes. If you're looking for where to watch and want to track when it lands on additional platforms, Movie OTT monitors streaming availability and updates as titles shift between services — useful for a Lifetime release still in its distribution window.
