Letty Raines (Michelle Dockery, “Downton Abbey”) is a thief and con artist who is always one bad decision from implosion. Fresh out of prison, she's attempting to stay afloat. But when she overhears a hit man (Juan Diego Botto) being hired to kill a man's wife, she sets out to derail the job, sending her on a wild collision course with the killer.
Letty is encouraged to seek help by her parole officer (Terry Kenney) to overcome previous bad behavior. She needs to keep on the straight and narrow in order to have visitations with her son, who is currently in her bitter mom, Estelle’s, custody (Lusia Strus). The premiere episode is titled “So You’re Not a School Teacher.”
