Sir Richard Wyndham, an accomplished Corinthian, is being forced into marriage by his family, who want him to have an heir. Depressed by the life laid out before him, he nevertheless agrees to this course. The night before he is to announce his choice he comes across Penelope Creed, a young girl in boys' clothes, hanging helplessly from an upper story window. She is a very wealthy orphan who is running away from her own distasteful marriage plans. The two become allies, leave London in search of Miss Creed's childhood sweetheart, and find themselves in the middle of a dangerous game of mystery, theft, and murder.
