Hetty Wallace has been tricked into signing a document that makes Major Shrapnel, an unscrupulous horse trainer, seem the owner of her horse, Blue. Hetty does not know the contract is illegal because it is unwitnessed. Then Shrapnel sells Blue, but the new owner is sympathetic to Hetty and investigates.
