 A former boxing champion, now an innkeeper, is accused of stealing a watch from a party of guests at his inn, who happen to be members of English royalty. The old man is arrested and thrown in prison. His son, knowing that his father didn t steal the watch and suspecting a frame-up, follows the royal party to London, where he poses as a wealthy "gentleman" and insinuates himself into the English court in an effort to find out who framed his father and why.
