Christy Plunkett

She is a single mother who has gone a year without drinking and is still struggling with addiction. Now sober, she tries to regain the trust of her daughter Violet, who is revealed to be pregnant herself in the first episode. Christy also has a younger son, Roscoe, and strives to be a good example to him. As if that were not enough, she is also trying to iron out the rough edges in her relationship with Bonnie, her mother, who never learned to play her role well, and who would rather go out and drink than baby-sit.
