Illegal loggers crack open a fog‑drenched cloud forest—and wake a matriarch that learned to hunt above the river. Dr. Eliza Ward (Scarlett Johansson), a wildlife virologist, teams with Jack Rourke (Chris Pratt), a tracker who knows the canopy like a map of scars.

Their rescue op turns gauntlet: rope‑bridge collapses, a flash‑flood night run, and thermal sights catching a necklace of cold scales weaving through the trees. The serpent adapts, using storm winds and echo to herd prey toward deadfalls.

Evidence mounts that this alpha isn’t alone—eggs, moved; trails, mirrored. Corporate mercs arrive with sonic lures and fire, forcing predator and protectors into the same crosshairs. Final beat: a hollow log blinks, and the forest holds its breath.
