This program uncovers a complex green society pulsing with communication, movement, sex and social interaction. From the heights of Utahs Great Basin Desert to the rainforests of Canada's West Coast, lead scientist and ecologist J.C. Cahill treks the green world and discovers that plants are a lot more like animals than we ever imagined. The world he reveals is one where plants eavesdrop on each other, talk to their enemies, call in insect allies to fight those enemies, recognize their relatives and nurture their young.
