His PITA of a sister was in charge while their parents were away, she teased and pushed him around until he was not going to take any more. Only his revenge did not quite go the way he had planned it.
Josh, while taking a break from his stocks and securities activities, encountered a troubled woman in Hawaii. He wound up in the middle of a debacle, between a sibling rivalry and an Adonis, but wound up making the trade of his life.
