Splatt, an adolescent water drop, lives in Sea Drop Village on the ocean floor at a depth where water has absorbed all the colors of the light spectrum and everything appears grey.

He is curious and somewhat rebellious, struggling to blindly accept the authoritarian dogma he is taught—from the dangers of entering the open ocean, to a required unyielding reverence to Thunder God, their creator, and finally the threat of death by painful evaporation should he rise to the surface. But most of all, he refuses to accept the doctrine that color does not exist.

Splatt becomes preoccupied with the fabled Colorland and convinces his girlfriend Lara to set out with him, under the cover of darkness, to find it. But only meters into their quest, they get separated by strong currents and carried in opposite directions. Both know the only way to reunite is to find Colorland. But the ocean is vast and home to diverse drop species that are often hostile. Success seems increasingly unlikely, and at times impossible.

The question is: is color found in the journey, the destination, or beyond?
