Who Am I? (movie, 1998)

A group of covert CIA operatives trailing a potential new energy source are double-crossed by corrupt agent Morgan, who causes a helicopter crash in remote South Africa. The sole survivor, suffering severe amnesia, is nursed to recovery by a kindly native tribe who call him "Whoami" after the question he keeps asking. With the help of a mysterious reporter Christine, Whoami pieces together his past and tracks the turncoat agent and his criminal cohorts.
