The next chapter finds Rambo recruited by a group of Christian human rights missionaries to protect them against pirates, during a humanitarian aid deliver to the persecuted Karen people of Burma. After some of the missionaries are taken prisoner by sadistic Burmese soldiers, Rambo gets a second impossible job: to assemble a team of mercenaries to rescue the surviving relief workers.

Rambo IV: In The Serpent's Eye is scheduled to be released in 2008.
