A king‑tide collides with a stalled hurricane, turning a Gulf‑coast town into a black‑water maze . Haley swears she’s done with crawlspaces—until a collapsed causeway traps first responders below street level and a poachers’ pen bursts, seeding the flood with hungry shadows .

Trailer jabs: a submerged motel corridor pulsing with neon sparks ; a jon boat spinning into a sinkhole ; eggs cracking in a church nave as thunder rolls ; rooftop leaps between billboards in 80‑mph crosswinds ; and a silent hunt through a school gym where bleachers hide teeth . Every breath is rationed, every splash a signal. To live, Haley must outswim the surge and outthink the swarm. Final flash: a red flare hisses—yellow eyes close in.
