Of all the notorious lawmen who ever patrolled the violent Texas frontier, none are more storied than the Texas Rangers. Being the only female ranger in this elite squad isn't going to stop ballsy, badass Molly Parker (Tricia Helfer). Molly is committed to finding the truth and seeing justice served. While she's surrounded by law enforcement colleagues who want to see her fail, including Police Lieutenant Estaban Salazar (Vic Trevino), the Rangers have her back, led by Company Commander Luis Zea (Alex Fernandez). Molly's also got her brother Billy (Michael Trucco) and his wife Nessa (Marta Milans). On the verge of getting divorced from her smarmy husband Jake (Jeffrey Nordling), Molly begins an affair with sexy DEA agent, Dan Winston (Marc Blucas).
