The titular character of Inch High Private Eye is a miniature detective (literally one inch high), who attained his diminutive stature by way of a secret shrinking potion. He often enlists the help of his niece Lori (sometimes written "Laurie"), her muscle-bound sweetheart Gator, and their dog Braveheart to help solve mysteries. Unlike most Hanna-Barbera mystery solving cartoons, the characters in this show are all adults.
