When Rainbow Fish and his friends attempt a dangerous sport called "Riptiding", Blue is swept away on a riptide, and Sea Filly and Rainbow must find him before it's too late.

In spite of some ongoing construction taking place outside the School Of Fish causing a big deal of noise, Rainbow is sent home early and gets freedom. A pair of burglars soon break into the Fish cave, and try to ruin it any way they can, all while Rainbow watches his favourite cartoon, "Silly Salmon" on TV by himself. Thanks to a 911 call being traced, Rainbow arrests the burglars and saves the day, pleasing Aqua and Sol in the process.
