Moll falls for a Roman Catholic and converts before marrying him. Travelling to his estate in Ireland, she finds her husband's "sister" was paid to find him a rich wife, as he is as broke as her. They part and she travels back to London, but the coach is robbed by a highway man. A fellow passenger offers to stand guard in her room for protection and becomes for financial adviser as well as her lover. Learning that his wife is a whore, she persuades him to divorce her so that they can marry. When his bank fails and the shock kills him, Moll must flee the bailiffs again and now turns to theft.
