In this color-drenched interpretation of Aesop's fable, a mouse, in colorful attire suitable for a night on the town, finds herself trapped by a caged lion in the city zoo. The mouse begs to be released and promises to help the lion one day. The lion is skeptical but releases her nonetheless. Later that night, the mouse returns with mouse friends—as spiffily attired as she herself—and together they unlock the lion's cage and prove that "little mice can be big friends."
