From hit-maker Chuck Lorre comes his next big comedy-an irreverent and outrageous take on true family love-and dysfunction. Newly sober single mom Christy (Anna Faris) struggles to raise two children in a world full of temptations and pitfalls. Testing her sobriety is her formerly estranged mother, now back in Christy's life and eager to share passive-aggressive insights into her daughter's many mistakes.

In the new season, Bonnie (Allison Janney) must learn to adjust without her daughter and former-roommate, Christy, around. With a chaotic past behind her and a newly empty nest, she focuses on her marriage to her husband, Adam (William Fichtner), and on what she wants to be now that she's finally grown up. Now more than ever, Bonnie depends on the support of her friends, including the wise Marjorie, the wealthy and sometimes misguided Jill (Jaime Pressly), the overly emotional Wendy (Beth Hall) and her foster sister, Tammy (Kristen Johnston), who was recently released from prison. Collectively, they help each other overcome their mistakes and stay sober in the face of whatever life throws at them.
