Happily splashing in the rain-spattered world beyond her windowpane, Vraily finds refuge from her parents' high-octane, hurry-up existence. But when she falls through a puddle, she's plunged into an underworld of harrying giants and perplexing dolphins, where she's left alone to find shelter from the onrushing storm. Finding an ally in her steadfast blue umbrella, Vraily discovers an unexpected strength that protects her from the deluge, and from the hustle-and-bustle of the everyday world to which she must ultimately return.
