When twins Dawn and Dusk, young members of the Amazon rain forest's Morning Tribe, discover that their homeland is being threatened by Global Agricorp mercenaries, they gather their friends and rise to the challenge of protecting it. Though they're naturally smart, strong, and quick, the twins also each have special abilities. Dusk is stronger, faster, and more powerful as the sun sets. Dawn is farther-sighted, a better swimmer, and a gifted acrobat as the sun rises. They are at the height of their power together at midnight. But young Tom Toll, estranged son of Agricorp's boss, ventures alone into the forest intent on destroying the people of the Morning Tribe, and finds himself in danger. He is saved by Dusk and Dawn and a deep bond forms between them as Tom gains an understanding not only of the forest, but of shared values and a greater global mission. When the trio of youngsters save Tom's father and the Agricorp crew, who are attempting to burn the rain forest, it changes the relationship between father and son into a positive one forever.
