The show takes a look at the heartwarming yet super uncomfortable and sometimes frustrating relationship among three adult siblings: one in the 1%, one middle-class and one barely holding on.

The Hayworth family is invited to the wedding of longtime family friend Spags. When Connor enlists Tom's help to write and re-write a wedding toast, things take an unexpected turn between the brothers. Sarah realizes Denise is upset they never had a real wedding, while Marina meticulously plans her drinking schedule for a night out without the kids.  

When Tom and Sarah discover that their parents have been spending time at Connor's house and not theirs, jealousy rears its ugly head. But when it looks like there might be more grandparent time for everyone, they learn to be careful what they wish for.

The family gathers to try and celebrate their parents’ anniversary without spoiling it — like every other year. However, after everyone learns what Tom’s new novel is about, the celebration may just be the worst one yet.

Marina worries Camila’s lost touch with her Mexican heritage, so she enlists Tom and the rest of the family to help reconnect with her roots. Prompted by Denise, Sarah interviews for a job at Gretchen’s school but receives some unwanted assistance from Connor.

Tom, Sarah and Connor are determined to prove that they can host a successful Thanksgiving dinner when they switch up their annual holiday tradition to gather at Connor's place. Denise has some sibling drama of her own when her sister joins the Hayworth family celebration.  

Tom and Connor vie to prove who would make a better sperm donor to Denise. Meanwhile, Sarah tries to prove to Alison that she has what it takes to direct the spring musical by throwing a successful fundraiser at Connor's house.

As Tom struggles to finish his book before his 40th birthday, his dad, Marshall, hijacks his writing seminar. Meanwhile, Denise convinces Marina that she needs to do something special for Tom's 40th and talks her into doing boudoir photos. In addition, Sarah and Denise go overboard to impress a potential sperm donor.

With a house full of Hayworths, nothing is off limits for discussion - including Tom and Marina's lives in, and out, of the bedroom. Connor's patience as host is running thin so as a thank you, Sarah and Denise strategize a creative way to show their appreciation.

Reflecting on the past, we flashback to Tom and Marina's wedding day. A defining moment in all the Hayworth's lives, this catastrophic reception proves that while you cannot have your cake and eat it too, family sticks together for richer or poorer, better or worse.

After the shocking discovery of a new-half sibling, Tom, Sarah and Connor are tasked with breaking the unexpected news to their parents. Meanwhile, Marina and Denise team up to confront Denise's stubborn landlord.

It's Thanksgiving at the Hayworths, though this year feels a bit different with one extra chair at the table. While Tom, Sarah and Connor wrestle with their conflicting emotions, Marina and Denise see this new addition to the family as a potential chance to gain a new "normal."
