Director Mercedes Bryce Morgan gives the middle finger to puritanism in this erotic thriller set on double entendre lake. Arriving at a glamorous country house on the titular Bone Lake, Diego (Marco Pigossi) and Sage (Maddie Hasson) are flabbergasted to find that it’s been double-booked by another couple. Enter the gorgeous, flirty and fancy-free Cin (Andra Nechita) and Will (Alex Roe), who propose that they all stay there together.

What starts off as a fun couples’ weekend takes a sinister turn when prudish Diego and Sage begin to butt heads with the more liberated Cin and Will. Already on edge due to the unspoken tension in their relationship, Diego and Sage become fractured by Cin’s attempts at seduction. Clearly, something is afoot here, and the creepy house with its secret rooms and buried secrets is just the start of it. What follows is perhaps more straight thriller than the erotic version as advertised, although fans of twisted mind games should enjoy what Morgan has in store for Diego and Sage. Think of a horny Speak No Evil by way of Barbarian, and you’ll find yourself in the general wheelhouse of Bone Lake.

While the story could have done more to subvert what seems to be happening, there are still plenty of shocks in store for the chaotic, gory endgame. Nechita and Roe have chemistry for days, while Hasson and Pigossi make for a more plausible (certainly plausibly repressed) couple. It’s almost a disappointment when the film takes a turn into more predictable stalk-and-slash territory, losing much of what made it so juicy in the first place.

Bone Lake isn’t as clever or subversive or even sexy as it thinks it is, but it has fun trying.

BONE LAKE premiered at UK FrightFest on August 24, 2025.
