At her father's memorial, heiress Eleanor Vance catches her husband Derek cheating with the maid. To cover up, the pair swallow dog transformation pills — not knowing Eleanor can understand every bark. She hears Derek mock their marriage and confess he provoked her father to death. Playing dumb, Eleanor has him neutered. A biologist botches the surgery, grafting rabbit testicles onto him. When Derek turns human again, he's publicly exposed, sterile, and trapped as a lab subject. Eleanor reclaims her inheritance, files for divorce, and discovers the heartbreaking truth: her father gave her the ability to understand dogs — a gift born from a childhood wish. In losing everything, she finds her father's love was always there.
