When Ken's attractive new intern, Erin, shows up at Welltopia, Allison starts to feel a bit insecure when Erin's admiration for Ken veers into flirtatious territory. Meanwhile, Damona's boyfriend, Eric, wants her to confront her musical past when he learns she was the lead singer on the C & C Music Factory's 1990 dance jam, "Gonna Make You Sweat". Molly's first date with Jae leaves her wondering if he really likes her, so matchmaker D.K. goes on a secret mission to see what he can find out.

However, these good intentions have a way of driving everyone crazy at both work and at home. Luckily, his therapist wife Allison is just the right partner to keep things sane.
