The Weasels are in love in the Wainscott Woods. Zeke Whitebelly loves Wendy Blackish, who admires Zeke for his whiteness. Bagley Brown, the "Wainscott Weasel," is deeply in love and obsessed with Bridget, a silver fish who says that "fish are meant for fish." Most of the major and minor characters are stereotypes-Zeke is the macho chauvinist, and Bagley is the brooding loner.
However, Wendy is an independent female who's not afraid to invite a man to a party or ask to lead when they dance. The plot revolves around these romantic interests and Bagley's attempt to save Bridget and the other inhabitants of the pond from the preying osprey. Bagley hatches a plan to move the bird's nest and nearly sacrifices his life carrying it out. He and Bridget meet one last time, and she says she realizes that what's on the inside is more important than the outside.
