Following the death of their childhood friend, three women make a series of life-altering decisions.

In a desperate attempt to prove she's fun, Sarah drags Amy and Jodie out on a night of hijinks. Amy struggles to balance a work crisis and her new dedication to motherhood and Jodie's anxiety takes over after sending a flirty text to Matt without a response.

Sarah begins to dip her toes into the dating pool and enlists Amy and Jodie's help in vetting a woman whom she ran across on a dating app. Meanwhile, Amy's maternal instincts are tested when she learns Luke isn't fitting in with other kids. Then, Matt comes to Jodie for business advice, causing her to reflect on how she's appreciated within her own family.

Sarah, Amy and Jodie's made-up annual holiday, "D-Day," celebrates a major moment from Beverly Hills, 90210. Jodie clings to every aspect of the tradition, despite Coleen's absence. Meanwhile, Amy attempts to use the holiday as a day of respite from her family and Sarah worries she's too old to get back into the dating scene.
