A cold case turns deadly hot when Texas Ranger Rory Yates goes on a no-holds-barred pursuit of a serial killer targeting young women.

Texas Ranger Rory Yates wears a five-pointed silver badge and travels his home state investigating unsolved crimes alongside local law enforcement.

Cruz, an officer with the Tigua Tribal police, is wary of Texas Rangers, but she and Yates forge an uneasy partnership when he joins her in investigating the disappearances of native women who have gone missing on the summer solstice over the past several years.

When a killer lures them to the edges of Texas's most unforgiving landscape, Cruz and Yates discover that they have more in common than they realize.
