By day, AWOL Navy SEAL Finn is hiding out on Vieques, a tiny island paradise off the eastern coast of Puerto Rico, living in a spare room behind a seafood restaurant owned by a blind local. By night he scours the dark web, hunting for the rogue officer responsible for the crimes he is accused of committing. But Finn's world is about to be turned upside down by a new nightmare, when his employer's two grandchildren go missing. To find them, he'll have to infiltrate the island's dangerous criminal underbelly and expose a shadowy crime network known as La Empresa-even if it means exposing himself in the process. As the children go on their own harrowing odyssey to stay one step ahead of a cop-turned-killer, a hurricane batters the coastline, cutting Puerto Rico off from the rest of the world. Taking his pursuit to the sea, Finn's skills and endurance will be tested to their limits to rescue the lost children and escape his own pursuers before the clock runs out.
