With Pop-Pop moving in due to a fire at his condo, Adam must bunk with Barry, who has returned with Erica to help Bev deal with Murray's death. Barry torments Adam like days of old and forces him to watch the film Field of Dreams multiple times. Adam uses baby monitors that Erica and Geoff bought for their pending child to prank Barry into thinking he's hearing the classic line from the film "If you build it, he will come." Barry and the JTP begin building a whiffle ball park in the back yard. Adam has a good laugh at Barry's expense, until he's told that the real theme behind Field of Dreams is the main character wishing he had one last "catch" with his deceased father. Realizing the film was Barry's way of grieving for Murray, Adam sets out to make things right. Meanwhile, Erica becomes upset when she sees Murray's favorite chair has disappeared. Beverly says she put it out to the curb as a means of closure, but when they go out to retrieve it, the chair is gone. Fortunately, they soon discover that Pop-Pop took the chair and put it in the baby’s room.

Geoff's father uses a jewelry eyepiece to look at Erica's ultrasound photo, and claims to know the sex of the baby. Though he and Erica agreed to be surprised, Geoff can't help but look. While he and Lou determine it to be a boy, Erica later peeks at her file folder and sees "F". thinking it's a girl. The doctor tells the couple that Geoff in fact saw a pinky finger in the ultrasound photo, while the "F" in the file was in reference to Erica, not the baby. The two recommit to not wanting to know the sex. Meanwhile, David Hasselhoff is in town to shoot some scenes. While Barry schemes to get an autograph, Adam visits Hasselhoff's trailer asking for a job. Hasselhoff refuses, but Adam lies to Beverly and says he got a job at the film site. After Beverly confronts Hasselhoff (bringing him a shrimp parm dish), he says he never gave Adam a job. Adam has to confess to Mom that he doesn't feel ready for college and wants to take a gap year. Mom understands, and they return to Hasselhoff's trailer. The actor tells Adam he can get him production assistant work, as long as Bev keeps bringing him shrimp parm.
