Henry Fisher's world changes forever when his parents get a divorce and his blind dad appears to replace him with a guide dog.

The arrival of the new guide dog forces Mel to reveal he is blind to a client; when Henry borrows the dog, a pretty girl thinks he is blind; when Joyce's study partner validates her as cool, Katie starts to see her differently.

When Katie rebels against her parents, Mel and Joyce must team up to teach her - and themselves - a valuable lesson.

Mel discovers he has trust issues when he and Joyce disagree over how to discipline Katey. When Katie goes missing, Mel and Joyce have to team up to find her. Henry, needing a break from his family's drama, forces Runyen to allow him to sleep over for the first time in their friendship.

When Mel thinks Henry is becoming a slacker, he takes him into work to show him what success looks like. Seeing his dad in action, Henry learns an unexpected lesson that helps him step out of his father's shadow. Meanwhile, Joyce and Katie decide that in Mel's absence, they need to stand up for themselves, which makes for a couple of bold, and embarrassing, confrontations in the returns department of a furniture store.
