Mom follows Christy, a single mother who—after dealing with her battle with alcoholism and drug addiction—decides to restart her life in California’s Sonoma County Wine Country working as a waitress and attending Alcoholics Anonymous meetings. However, her history also happens to run in the family: her mother, Bonnie, is also a recovering drug and alcohol addict, and her 16-year-old daughter, Violet has begun to follow in Christy’s footsteps by sleeping with her boyfriend, Luke, resulting in an unplanned pregnancy that parallels Christy’s, who gave birth to Violet when she was Violet’s age.

Christy also has a younger son, Roscoe, whose father, Baxter (her ex-husband, as Violet has a different father), is a deadbeat, and drug dealer. Christy also dates Gabriel, her boss at the restaurant (who is also married but wants out despite having a father-in-law who owns the restaurant), and Rudy (a critical chef who takes his job too seriously). On the latest episode, Christy is determined to take things slow in her relationship with Adam. Meanwhile, Bonnie and her rival from AA, Marjorie, disagree on what taking it slow means. Justin Long returns as Adam and Mimi Kennedy returns as Marjorie. Keep watching to see how the relationship develops!
