North and South Limbawe are in conflict over oil and a despotic General plans to overthrow his own government in South Limbawe and attacks his neighbors to the North. String and Dom are sent by Archangel to aid North Limbawe and it's leader, Seku Logana, but Logana has his own prejudices about receiving aid for his cause. Also in the mix is an old Vietnam buddy of Hawke's, Marty Vidor, who is working as a mercenary for South Limbawe, and Hawke is hesitant to take him on since Vidor just may know the location of the missing Saint John.
