At the elementary school, the third graders play in the art room and the Mortician's Club is practicing mummification. Suddenly, Cheryl enters and says that the third grade field trip is coming, and they have decided to go to the Lake St. Byron beach. This announcement makes the third graders cheer, but makes Lucy announce an emergency meeting. At the Royal Woods Cemetery, Lucy holds the meeting, and states that they must find a way to prevent going to the beach, not wanting to endure the sun, sand and sports. When Haiku points out the trip is mandatory, Lucy says it doesn't mean they can't stop it.
Throughout the day, the Mortician's Club attempt to persuade Principal Huggins and Cheryl into going somewhere else for the field trip like an oddity museum, the cemetery or the morgue. However, their attempts only either scare their principal or make Cheryl remind them that the beach has already been finalized. The club then tries to trick Huggins into canceling the trip by making it look like there's a thunderstorm, but Cheryl pointing out the sunny sky and Norm taking his hose back causes the charade to fall apart. As the third graders and the club board the bus, Lucy resorts to one last tactic. Opening a box, Lucy unleashes a swarm of bats to scare Huggins and the bus driver, leaving the vehicle with no driver. However, Cheryl reveals that she can drive the bus, ultimately making the Mortician's Club accept defeat and go to the beach.
As the bus arrives to the beach at Lake St. Byron, the third graders run off to have fun, and the club quickly put up a tent to shield themselves from the sun. As the club hides in the tent, a pelican arrives and convinces Fangs to join him. Donning an umbrella, Lucy proceeds to get Fangs back. During her search, she ricochets a volleyball that goes over the net and leaves the third graders impressed. Although Lucy admits how good it felt to hit the ball, she saves face and grabs Fangs before heading back to the tent to tell her members of her "horrifying" search. Not long after, Fangs sneaks off to have fun, prompting Lucy to go after him again. This time, she runs into a girl who's crying over her ruined sandcastle, and Lucy decides to help her make an even better sandcastle. Attempting to save face again, Lucy quickly tells Fangs to come back to hide from her fellow classmates that she's having fun. Upon entering the tent, Fangs sneaks off at Lucy's request, and Lucy feigns frustration that Fangs left again, and proceeds to go after him, where in actuality, she uses this as an excuse to have fun with the third graders. Fearing that something bad has happened to Lucy, the remaining club members exit and discover Lucy having fun by surfing. Realizing she has been caught, Lucy loses her balance, washes up on shore, and the club disowns her for being a "normie." Catching up with her club members, Lucy apologizes by telling them that while she likes the beach, she's still the same person she has always been, and that they should at least give the beach a chance.
Sometime later, the Mortician's Club is revealed to have a fun time at the beach, partaking in several fun activities.
