Will Zachary leads an isolated existence running The Flying Z, a struggling, southern Arizona ranch on the Mexico border, with his aging, dementia-stricken Uncle and a ragtag crew of of fellow cowboys and town folk. His ordered life dramatically changes when Merry O’Hara, driving cross-country on her way to grad school at Stanford, takes a wrong turn into a ditch on his land…and right into the middle of a war he’s fighting with a vicious cartel smuggling drugs across his ranch. Against all odds, Will and Merry are drawn to each other, at the same time they’re desperately fighting, out-manned and out-gunned, to protect the ranch and their lives.
