Of all the notorious lawmen who have ever patrolled the violent Texas frontier, none are more storied than the Texas Rangers. But being the only female ranger in this elite squad isn't going to stop ballsy, badass Molly Parker. 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 Guillermo Salazar, the Rangers have her back, led by Company Commander Luis Zea. Molly has also got her brother, and his wife Becca. On the verge of getting divorced from her smarmy husband, Jake, Molly begins an affair with sexy DEA Agent Dan Winston.
