A gold coin interests explorer Dirk (Matthew McConaughey Matthew McConaughey) because it is inextricably linked to a treasure legend. Dirk, an adventurous man who could not stop for a moment, embarked on a tortuous adventure along the Nile in Africa, peeling off the secrets of the gold coin. More crucially, he also discovered a great crisis that could endanger the destruction of the earth by mankind-a dictatorship in Africa colluded with local tycoons to dump nuclear materials into the sea. The local people have suffered so much that they are out of their minds, and if they do not act in time, the danger will expand rapidly. Dirk and Eva (Penelope Cruz), a female scientist, wage a just struggle together. They have to face the evil forces and the difficult natural environment, and risk each other all the way.
