While in the Army, Jim achieves the rank of Captain in the US Army Rangers, working covert ops. His last mission (for 7th group special forces - ODA 731) takes him and his team of seven to Peru to stop a drug-smuggling campaign. Unfortunately, his ranking officer was corrupt and set him and his men up for failure. His helicopter crashes, killing his seven men and leaving him wounded. He is taken in by the Chopec, an elusive and secretive tribe in Peru, and learns to control his senses for the tribe's betterment under the tutelage of Incacha, the tribe's shaman, who calls Jim "Enqueri" ("Sentinel"). The following year, when a satellite photo shows seven tombstones at the helicopter's crash site instead of just a pile of scrap metal, the US Army sends in a team to find the sole survivor of the crash and bring him back home.
