She's a detective in Oklahoma. She has lived her life in fast-forward. She's a legend in law enforcement, a take-charge, no-consequences kind of cop who rarely thinks about her personal life. Maybe she doesn't want to slow down. Maybe it's because she's seen too much misery on the job. Maybe it's because she's experienced her own share of tragedy. Maybe when she's alone, she feels pain and loneliness. Over time, she's developed a reckless streak. She drinks too much. She sleeps with the wrong men. She openly defies her superior's authority. She plays by her own rules. And she shows criminals no mercy. In fact, she once held a perp hostage in her apartment for three days. Nor does she suffer fools among her colleagues, including her partner, who is also her lover. One night, fate plays a trick on her. She meets a fallen angel. Yes, the kind with wings that sometimes pop out unexpectedly. She gets assigned a thankless task: to train, assist and guide her back to the straight and narrow. Unsurprisingly, this proves to be a monumental challenge.
