In the eternally busy city of Din, the black-and-white Rushers constantly go about their business in a fast-paced way and stop only to sleep, due to their Cosmic Clock being wound too tightly. Din lies between two worlds that create dreams to deliver to the sleeping Rushers – one is the bright and cheerful Frivoli, where Greensleeves and his Figmen of Imagination bring sweet dreams; and the other is the Murkworks, a dark and dingy factory home to vultures who drop nightmare bombs. The evil Botch, maniacal ruler of the Murkworks, wants to foil Greenie's efforts and subject the Rushers to non-stop waking nightmares. He uses his vultures to kidnap the Figs and Greensleeves, but not before Greensleeves writes an S.O.S. to Frivoli.
