To the families of St. James Catholic School in Torrance, California, Sister Mary Margaret Kreuper and Sister Lana Chang were the picture of morality and religious devotion.

The Opportunist tells true stories of regular people who turn sinister by embracing opportunity. How does an everyday person turn into a thief, a scammer or a cult leader? Perhaps the most dangerous person is the one who appears the most normal. Perhaps there is a dark potential lurking inside all of us that is just waiting for the right opportunity to emerge. The Opportunist is an original podcast hosted by Sarah James McLaughlin.
