Maura finds solace with ex-wife, Shelly, and the two hatch a plot to help Ed realize his wishes. Sarah spends time with her ex-husband and begins to question their breakup. Raquel finally breaks through to Josh. When all members of the family are summoned to Shelly's, they are in for a few surprises.
In a flashback, Mort escapes with a friend to a cross-dressing retreat in the woods, and becomes captivated with a very accepting woman. Left alone after cancelling her Bat Mitzvah, 13-year-old Ali finds trouble with an older man at the beach.
