The small residents of the coral city are preparing for the most important night of the year, where they will unite in the annual breeding spectacular. But these tiny animals must overcome huge challenges if they are to make it to the main event. The peacock mantis shrimp is in a race against time and interruptions, as she tries to build the perfect burrow for her nursery. The very hungry little cuttlefish is eating as much as possible to build his strength, whilst trying to avoid being eaten himself. And the clownfish dad is obsessively tending his eggs, so they hatch at the perfect moment. But their whole world is in grave danger; an invasion of giants is threatening to destroy the living reef itself. And in order to overthrow them and secure the future of their coral city, the little critters must join together.
