In TopKnotch, three Shih Tzu girls—Ginger, Hapi, and Missy, scheme to extricate their late 20's-something owner, Robin, from a series of foibles. Robin is an engineer who works for her user-successful, but domineering dad, Fritz. She's engaged to marry Sean, who works as the intellectual properties attorney for their firm, Rosencratz & Dessein. Determined to connect Robin with the man of her dreams, they are always on the prowl for a new boyfriend to replace Sean.

Luck is with them when Robin meets Luke at a backyard pool party. Luke is a world-renowned engineer and inventor, and unlike Sean, he's a really nice guy. Much to the dogs' delight, Luke has super powers and can hear them talk! Hi-jinx ensues as the dogs scheme and conspire with Luke to connect with Robin. As Robin becomes increasingly torn between Luke and the "papa-approved" Sean, she discovers a few secrets of her own and learns life is lived from the inside out by being brave and following your heart.
