Two polyamorous couples are redefining what it means to be a family as they raise their four children together under one roof. With a new baby on the way and the dads butting heads about parenting, the quad struggles to get on the same page.

While in Portland for Taya's birthday, the quad gets wild in a hot tub. Taya confesses that she's interested in a connection with another woman, and Sean and Tyler come face-to-face about their son's paternity.
