To spice up their lagging sex life, Bobbi Hubble concocts a plan to get her husband Stanley sexually aroused by putting him in close proximity of their daughter Didi and then dragging him off to their bedroom and performing a role-play where she pretends she's Didi. She rents a lake house for her family so their bodies will be exposed in swimsuits. Didi complains that she has to leave her BFF Grace Gomez behind. Their son Chet is upset that he's missing chess practices before the big tournament.
On day six, Stanley and Gomez are interrupted when Lacey, Gomez's mother, arrives from another real estate outing.
The best laid plans of getting laid can succeed with unexpected partners.
