Early summer in Canada, Yukon River. Small, white mayflies swarm and dance wildly on the river surface. A single rainbow trout jumps across the choppy river surface to prey on the mayflies. In the early summer sunshine, the trout's body sparkles and splashes of water. A powerful scene. The camera focuses on the movement of the rainbow trout and the splashes of water. High-definition, realistic, detailed depiction of an early summer mountain stream with a swarm of mayflies dancing.
