Torn from his life in the Caribbean, Flitch, a tropical-hybrid fish, finds himself half a world away and dumped into Ocean City Aquarium, a tourist-centric hub of amusement-park worlds where fish of all types and sizes are the main attraction. Swimming among foreigners that don’t speak the language, Flitch makes a daring escape to other lands within the aquatic park, building friendships along the way. With the guidance of the Man in the White Shirt, and a surrogate parent in Old Man Crab, Flitch and his friends find a home together and learn that family is what you make it.
