Written by Michael Hirst, this series is an epic romantic adventure based on the life of famous American outlaw Billy the Kid, also known as William H. Bonney — from his humble Irish roots, to his early days as a cowboy and gunslinger in the American frontier, to his pivotal role in the Lincoln County War and beyond.。两对夫妇发现他们的孩子在出生时就被调包,由此面临道德困境:是继续养育没有血缘的爱子,还是找回他们的亲生孩子?。
