Andy guilts Will into agreeing to babysit Marcus so Fiona can go on a job interview, but the situation gets complicated when they receive a last-minute invitation to a once-in-a-lifetime charity pool party hosted by rap star Lil Jon. Meanwhile, Fiona discovers that honesty isn't always the best policy when it comes to landing a job.

Marcus asks Will for advice on how he can get Hannah to invite him to her upcoming birthday party. When that proves unsuccessful, Fiona takes it to task with Joanne, Hannah's mother, who also happens to be the queen bee of a group of neighborhood moms that she is trying to win over.
