Casanova

Freelance thief Casanova Quinn is the black sheep of the family--his father runs an international spy organization and his twin sister is the agency's top agent. When his sister dies during a mission, Casanova returns for her funeral, only to be shifted to a parallel dimension by a criminal mastermind. As his dimensional counterpart is a highly decorated and recently deceased agent, Casanova finds himself crossing and double-crossing both agencies, including his timeshifted evil sister, to return to his own timeline.
