Filigree may be a small puff of a Pomeranian but he has a big, brave heart. As the Revere family dog, he's ready to do his part to help the American colonists stand up to the British soldiers. But the other dogs, like Jove, Sam Adams's Newfoundland, and even the Revere cat, Anvil, think Filigree is a joke. The Reveres' daughter Frances is the only one who believes in him.

When Frances's father, Paul Revere, leaves home on a secret mission, Filigree and Frances know they have to help, no matter how dangerous it might be. Will a pint-sized pup just be in the way, or can Filigree prove that even a very small dog can fight for freedom?
