In the next three episodes the journey moves into three radically different worlds where survival depends on mastering water, ice and extreme seasonal change. In the Amazon, giant river otters hunt as a family, black caimans ambush newly hatched turtles, army ants sweep through the forest in highly organized raids and a harpy eagle guards a vulnerable chick high above the jungle floor. The rainforest emerges as a vast living system, shaped by rivers, floods, towering trees and countless species competing for food, space and the chance to raise their young. The story then heads north to Alaska and Canada, where polar bears wait for sea ice, wolves struggle through blizzards, hares evade lynx and immense caribou herds cross dangerous meltwater rivers during their ancient migrations. Finally, along the Gulf Coast, flooded swamps and subtropical wetlands become the stage for black bears, alligators, manatees, burrowing owls and one of America’s rarest wild cats, the ocelot. From the frozen Arctic to the humid marshes of Louisiana, Florida and Texas, these episodes reveal how animals adapt to landscapes that can change completely from one season to the next.
On 21 December 1988, Pan Am Flight 103 explodes over Lockerbie, Scotland, killing all 259 people on board and 11 residents on the ground. What follows is one of the largest and most complex terrorism investigations ever undertaken in Britain, forcing Scottish detectives and the FBI to work across borders, sift through an enormous debris field and reconstruct how a bomb was placed aboard the aircraft. Based on real events, the series follows both the painstaking search for those responsible and the devastating impact of the attack on the town of Lockerbie and on families on both sides of the Atlantic. In the first three episodes, the investigation begins amid chaos as police recover bodies and fragments of the aircraft while international pressure mounts for answers. Early clues lead investigators toward possible suspects and networks connected to the bombing, but every breakthrough raises new questions. When Scottish officers travel to the United States with potentially crucial evidence, tensions emerge between agencies, particularly over intelligence the CIA may be withholding about a possible bomb maker. The result is a gripping reconstruction of an inquiry in which forensic evidence, international politics and competing intelligence interests collide, while the families of the victims wait for the truth.
