As a hurricane threatens the coast of Texas, a woman from El Salvador and an American man looking for answers struggle to stay one step ahead of a violent ex-con bent on tracking them down.

Sofia Ramirez, fleeing violence in El Salvador, has succeeded in reaching the U.S. but at a terrible cost: the loss of her 3-year-old son, taken from her by immigration authorities when she crossed the border. Six months later she still has no idea where he is.

Mark Judd arrives on Mustang Island after a friend disappears while investigating Sofia's boyfriend Carlos Ruiz, a drug trafficker and owner of the bar where she works. He hopes that Sofia will be the key to learning what happened to his missing friend.

At first Mark and Sofia are wary of each other, but when he stumbles into danger, she comes to his aid, putting herself in Carlos' cross-hairs. With a hurricane bearing down on them and on the run from Carlos, they must turn to each other if they want to survive . . .
