After years of questionable choices, single mom Christy Plunkett (Anna Faris) is now sober and trying to get her life on track. It’s challenging especially because she lives with her mother, Bonnie (Allison Janney), who Christy still considers the root of her troubles despite the fact that she has also gotten sober. Now mother and daughter are working to overcome their past mistakes and build a better future for their family. Christy has gone back to school and is pursuing her dream of becoming a lawyer, while Bonnie attempts to have a healthy romantic relationship and figure out what she wants to be when she grows up. Through all of this, Christy and Bonnie rely on their support system from AA, including wise Marjorie, the wealthy and sometimes misguided Jill, and the overly emotional Wendy. Together they help each other stay sober and face whatever life throws at them.
