From the shore of Ko Phi Phi in Thailand to a suburb in Utah to a mysterious Kafkaesque hole in the ground, carried away on the crest of a wave gives us brief glimpses into the lives of a sphinx-like escort, a grieving father, a conflicted priest, brothers of legend, a felonious housewife, an accountant of time, an orphaned boy, a radio shock jock and a man who finds things. Each are connected, primarily, by the cataclysmic 2004 Indian Ocean tsunami that claimed the lives of over a quarter million people. In a series of vignettes, carried away on the crest of a wave illustrates the ripple effect of one of the deadliest natural disasters in recorded history and ponders what happens when the events that bind us together are the same events that tear us apart.
