This film explains how the sun's changing position in the sky throughout the day and season-to-season affects animal and plant life and the earth and weather. From the moment the sun rises, animals are waiting, ready to take advantage of the opportunities that the sun creates. A quirky chameleon uses solar power to survive, while a family of lemurs get a morning heat fix. But, as the day progresses and the sun climbs higher in the sky, becoming more powerful, animals must also react as it pushes them toward moments of crisis.
