Gruff scientist Jean Campagna (Jean Reno) is escorting Wanu (Harrison Lowe), an Amazonian shaman, around Paris, and is dismayed when his charge decides that there is something special about François Perrin (Patrick Bruel), a sleazy gambler they meet by happenstance. Wanu asks François to return with them to South America to find his soul. François, thinking he has stumbled on an easy way to escape his loan sharks, agrees, but finds the jungle unexpectedly perilous.
