It has been years since the man once known as Tarzan (Skarsgård) left the jungles of Africa behind for a gentrified life as John Clayton, Lord Greystoke, with his beloved wife, Jane (Robbie), at his side. Now, he has been invited back to the Congo to serve as a trade emissary of Parliament, unaware that he is a pawn in a deadly convergence of greed and revenge, masterminded by the King of Belgium’s envoy, Leon Rom (Waltz). But those behind the murderous plot have no idea what they are about to unleash.
