A giant silverback gorilla king named Titus caresses his infant. But he is no gentle giant. This 400 pound ruler has massive strength and a powerful chest. Wise and powerful, the silverback sovereign commands by his sheer presence, and it's his job to maintain order in his clan. Yet rivalry is erupting in his own kingdom. Soon, he may be reaching the end of his reign. What would happen if he were deposed? His own son, Rano, is out to take his father's place as king. Will he succeed?

In a secret kingdom, conflict divides a family. Brother fights brother with politics and scheming for the throne. Freud, the leader, is in his prime extremely smart and in control. But already, there is dissent within the ranks. His brother Frodo, the biggest chimp in the group, has become his rival. We watch as Frodo and Freud battle it out for the ultimate prize: control of their chimp kingdom.
