Taking the final leg of his trip in a one-engine plane run by Declan (Ewen Bremner from "Trainspotting"), Beck finds the kid easily enough, but handcuffing him and ordering him into a truck that would lead to the runway and a return to the States is not so easy. Travis does not want to return nor should he be forced to, considering that he is not a minor subject to his dad's rule nor is Hatcher willing to release the lad from the area given the boy's knowledge of the hidden treasure that Hatcher could fence for millions.

Many of the adventures that the two run into on their way north include conflicts with their human enemies, with hostile monkeys baring animatronic teeth, and most of all with nature in the form of explosive methane gas, landslides, and water. A good deal of the picture is taken up with fights usually won by Beck, including the night-club knocking out of an entire pro football defensive line which came to the defense of a fellow who is owed a gambling debt, a setback in which Beck is knocked out not by people but by a fruit offered to him by the local barkeep, Mariana (Rosario Dawson), and a humiliating series of knockdowns at the hands and feet of an Indian kick- boxer who barely comes up to Beck's chest and tips the scales at maybe half of what The Rock might weigh.

The highlight, a expected, is Sean William Scott in the role of Travis, a performance not entirely different from his wise-ass guise in the American Pie trilogy though in the jungles he has a four-day beard which seems not to grow even while handcuffed and presumably unable to use a razor. The movie sticks to the summer formula, coming alive principally when Scott issues his bon mots though of less interest during the dizzying fast-editing so endemic to films involving hard physical conflict.
