Tom and Jerry are on a cruise ship heading to a tropical Caribbean beach, and Tom looks out the window seeing a surfer riding a wave. Tom leaps for joy and dashes preparing for surfing and wakes up Jerry. Tom carries his surfboard out to the deck, but runs into many bumps and falls until he finally makes it to the sea out of a fishing boat. Tom lands on a large blue lump that reveals itself to be a shark. Tom peers over at the other surfers and hits the shark on the head seven times until his head has four lumps, knocking him out.
Tom surfs a large wave until he spots the shark below him, laughing demonically. Tom pulls himself up to the top of the wave until he is sucked beneath the water and soon encounters the shark again. Tom turns his arms such that he rows with them and speeds away from the shark, launching a foot into the air. He taunts the shark again, but scrapes the sand and runs into a rock. A mound of sand covers him and the surfboard is up against the rock, giving the mound the appearance of a grave. Jerry walks onto the "grave" and drops a flower onto it. He takes off his hat as a salute but grabbed by Tom, who spits out the flower. The sand comes off Tom's head and discovers that it is shown a red starfish has grabbed a hold of it.
The starfish makes a pose and takes off the hat before Tom attempts to remove the echinoderm. After much tugging with the starfish, Jerry whispers a plan in Tom's ear. The starfish protests, but fails when Tom carries him out anyway: Running headfirst into a big rock. The starfish is still here, and as Tom cries and points to the rock and his head, until a bump forms, which means that the impact pushes the starfish off.
Tom takes one last look at the starfish, and leaps excitedly, but turns around when joy doesn't last for too long as he sees Jerry has taken his surfboard and becomes annoyed. Jerry does a sombrero dance with the hat, puts the hat back on, and poses, but fails when Tom takes the surfboard and waves at the mouse. Jerry flies through the air and lands into a coconut tree. Jerry gets his head lodged in a coconut and stumbles around the beach. Tom paddles away, but soon encounters the shark yet again, jumping off his surfboard and swimming to shore, causing the board to fly into the shark's mouth. Tom laughs himself silly, but fails to watch as the shark expels the board and ends up throwing it into Tom's mouth. The shark laughs maniacally as he departs. Tom is then used as a surfboard by Jerry. He shrugs and decides surfing is surfing.
