An expert reveals how sharks sense rather than look for prey, and the team discovers that hordes of surf-seeking humans are haplessly wading into a feeding frenzy that’s been going on for eons.

The team investigates incidents off Maui in peak tourist season to discover why the island has more shark encounters than the entire Hawaiian chain.
