A community of land crabs underneath a New Jersey beach boardwalk often play host to a community of sea crabs that come to the land for vacation and both species of crabs can't stand each other. Armen, a timid land crab, is reluctant to go out and socialize due to how his mother and father died in a storm when he was younger and his rotting shell, inhabited by a fun-living organism named Anemone, is the only reminder of them. However, three muscular crabs and Armen's friends, Bobby, Manny and Jimmy, drag him to a club owned by his uncle Bruno. The crabs get into a fight with an arrogant sea crab named Mako when Armen inadvertently bumps into his would-be girlfriend, Ramona. The land crabs get evicted as a result and Armen frustratedly takes his leave. As he is sulking by the seashore, Mako and his goons come to hassle him and steal his shell. Ramona intervenes, but she and Armen get swept away in a high tide that ruins the land crab civilization.
Armen ends up in the far end of the beach and above the boardwalk where he is captured by a human collector to sell as a pet and is given an artificial shell to boot. He soon reunites with Ramona and together, they escape and work together to get back home. On their journey, they each share their insecurities, Armen for being to frightened to do anything besides stay in his shell and Ramona from wanting to get away from her overbearing mother Val, who expects perfection from her. Armen and Ramona's disappearances soon intensifies the rivalry between the land and sea crabs, mostly due to how Mako made up the story of how Armen tried to steal Ramona way from him. Bobby begins second-guessing his tendency to use physical force against his enemies and soon encounters Ramona's deaf sister Shelly looking for Ramona. However, as he walks her home, Val sends him away and when he tries to break up a fight between his friends and Mako's gang, he snaps off Mako's arm. Mako vows revenge and claims that Armen is dead, giving them Armen's shell. The land crabs then declare war.
As Armen and Ramona fall in love, two of the crabs they met while at the pet shop begin judging them, making Armen feel hesitant about his feelings, much to Ramona's distress. Eventually, Ramona begins to get dehydrated and passes out, prompting Armen to carry her into the water, moving past the conflict between the land and sea crabs, who cease their fighting to see Armen carrying Ramona and dragging her into the water. Ramona wakes up and kisses Armen and they go back to the surface where Armen is praised for his heroism and Mako is outed as a liar. The land and sea crabs work past their differences with Mako giving Bobby a new shell as a peace offering and Armen giving his shell to a new crab who needs it more.
