Like millions of millennials, Mike and Martina's two daughters move back home after college and they all have to deal with the new reality.

Mike and Martina haven't had sex since the girls moved back in and they're not sure why. Each tries to spice things up in their own way. Stella coaches Shea on how to snag boys with a dating app.

When Mike's step-brother Ethan comes to town, Mike has to deal with Bob's blatant favoritism. However, Mike soon learns that Ethan has secrets and is not doing as well as Bob thinks. Stella and Shea team up to beat their parents at family game night after learning that they had been letting them win all these years.

Mike learns that Kyle, a guy who bullied him in school, is now in prison. Shunning his father's advice, Mike decides to pay Kyle a visit (with Martina in tow) to show him how well his life has turned out. This inspires Stella to meet up with a nerd she once bullied named Elliot so she can apologize to him, but it leads to something else.

Mike and Martina set their friend John up with a new girl in order to "Frankenstein" the perfect friend-couple, but when John's ex finds out about it, the whole thing blows up in their faces. Shea, Stella and Ethan take over Bob's bar.
