Thrash hit streaming on Friday, April 10, sending Phoebe Dynevor’s Lisa into a flood-swamped South Carolina town where levees fail, water rises fast and she goes into labor in the middle of Hurricane Henry. As the storm rips through the coast, she gives birth in surging water and tells the baby, “Mommy’s here. Mommy’s just gotta fight some fucking sharks.”
The 1 hour 26 minute, R-rated thriller comes from writer-director Tommy Wirkola and drops its cast into a setup that is half disaster movie, half creature feature. Dynevor leads a lineup that includes Whitney Peak, Djimon Hounsou, Matt Nable, Andrew Lees, Stacy Claussen, Alyla Browne and Dante Ubaldi, while the plot adds bull sharks and a hungry pregnant great white to floodwaters that have already swallowed the town.
At the center is Lisa, who works in the offices of the McKay’s Meats plant and has been alone since moving thousands of miles from home for a jerk fiancé who ran off. Her mother has tried to steer her toward a water birth, but Hurricane Henry gives her no time to plan anything at all. The movie also follows Dakota, 18, who lost his father when he was young and then lost his mother more recently, leaving the agoraphobic teenager to shelter in place until marine biologist Uncle Dale can reach him by boat two hours up the coast.
That mix of survival drama and shark mayhem is what Thrash is selling, and it is why the film has been framed as a climate change disaster thriller rather than a standard monster movie. It is also why Sony stepped away from a theatrical release before the movie was picked up by Netflix, where it arrives as Atlantic hurricanes grow more frequent, more intense and longer-lasting. The film borrows the locked-in dread of Crawl and pushes toward Sharknado-adjacent absurdity, but its basic engine is simple: a storm, a birth and a mother forced to keep moving while the water keeps rising.
Thrash does not ask whether Lisa can outwit the storm. It gives her a worse problem and answers it the way the movie does everything else: by making survival a fight she has to finish one breath at a time.
