Michael Shannon, a corporate lawyer from Vancouver, is in Costa Rica on business. He goes to a resort on the west coast for a few days of relaxation while waiting for some government approvals. What was to be a relaxing vacation embroils him in the chaos of a local drug war as he is forced to call upon long unused skills from a time in his past when he was a soldier. His mind flashes back to that time and to Pamela, a woman he met while training at the Australian Tropical Warfare School.
