Across the U.S. coastline, a new phenomenon is emerging as great white sharks are captured on film breaching in California like never before. Filmmaker Jeff Kurr, marine biologist Alison Towner, and cinematographer Andy Casagrande set out to capture this unprecedented behavior and uncover the secrets behind the Great American Breach.

Shark researcher Dr. Neil Hammerschlag, joined by Shark Week expert Paul de Gelder, leads a team on a high-risk mission to track down "Big Rose," a record-breaking great white believed to be one of largest predators in the North Atlantic. Using innovative tagging technology and daring field operations, they venture to a newly discovered shark hotspot off Nova Scotia aiming to transform our understanding of these ocean giants.

Shark attack survivor and advocate Paul De Gelder teams up with apex predator specialist Rosie Moore in Jupiter, Florida to investigate what triggers giant bull sharks to confront humans, testing human behavior in the ocean, extreme weather events and prey preferences to determine what factors ring the loudest dinner bell.
