Series 1: 1. The Atlantic Coast

Wild and urban worlds intersect in unexpected ways along North America's Atlantic coast. On North Carolina's Outer Banks, an ageing stallion's battle to defend his family reveals the intense, unseen dramas of wild horse life. In Chesapeake Bay, rare footage captures bald eagles chasing ospreys midair for a hard-won meal. Beneath the waters of the 'Graveyard of the Atlantic', sand tiger sharks act as unlikely guardians for schools of scad fish, a behaviour only recently observed. In New York City, a young raccoon learns the challenges of urban survival in a vertical world while under threat from predatory red-tailed hawks, something seldom seen before. In the Appalachian forests, young black bears forage and fireflies light up the darkness, and in New England, a 130-year-old red oak tree’s preparation for winter is captured in stunning macro detail, revealing the intricate changes within its leaves.
