Of all the notorious lawmen that ever patrolled the violent frontier, none are more storied than the Texas Rangers. Molly Parker is one of the first women to join this elite group of law enforcement agents and is committed to finding the truth and seeing justice served. In a male-dominated world, she is aided by her sixth sense for why women kill -- rarely out of hatred, usually for what they love. Standing squarely behind her is her boss, Company Commander Luis Zea. Molly also has the support of her loving family, including her brother Billy and his wife Becca. On the verge of getting divorced from her narcissistic husband, Jake, Molly relishes her newfound freedom as she begins an affair with a sexy, dangerously handsome DEA agent, Dan Winston.
