In the final film in the Chameleon trilogy, the genetically-engineered agent Kam must thwart the plans of her evil twin brother.

To stay out of the slammer, down-on-his-luck bounty hunter Vince Holloway reluctantly agrees to do the bidding of two crooked IRS agents. Tasked with recouping $20 million of laundered drug money, Holloway heads south of the border to the Blue Iguana, a bar crawling with thugs, killers, smugglers, evil women, and crazy action.
