A public flame-out forces 20-something alcoholic Sam to move back home with her overbearing mother, Carol. Surrounded by all the triggers that made her drink, Sam tries to move past her worst self and figure out her best self. Kinda.

Sam scores a victory when she lands a job interview in New York with an unlikely ally, only to discover how scary it is to write while sober. Concerned that her daughter needs help, Carol breaks a boundary and introduces herself to Olivia.

Sam and James travel to New York. While there, Sam is confronted with memories of who she was before sobriety and must decide whether she can risk being Old Sam again. Olivia and Stephanie take an important step in their IVF journey.

Sam's newfound self-confidence is shaken when she learns her new boss is a blast from the past. Meanwhile, Felicia errs in how to congratulate her boyfriend on his promotion. And Olivia makes a life-changing decision.

Sam questions if she can move on at work from her old self while also trying to navigate a relationship with a "normie." Carol snoops around Sam's room and makes a terrible discovery. Joel and James have a night out.

After Sam learns that Carol has invaded her privacy, the two have an explosive fight, leaving Bob to try to mediate. And just as things are going well with Peter, Felicia gets an unwelcome visitor from her past.
