Isabelle is captured by Lieutenant Morlais (Wright) and sent to a horrible island prison. Before leaving she passes Rev. Trent (Lee) a locket and tells him to give it to David Grief as a keepsake. Inside is a picture of Isabelle along with a clue ... It is believed Isabelle may know the whereabouts of some stolen gold. Grief and Mauriri are led to believe she may be innocent of her crime (of killing her lover) and plan a prison break.
