All Christian White wants is a quiet life. So when Billy Sutherland, Christian's old friend and sometime guardian angel from their 1960s hippie days, asks Christian to help him collect on a 40-year-old IOU from his shady past, Christian does everything he can to talk Billy out of it. Because the IOU is for a huge load of high-grade hashish. The hash is in war-torn Afghanistan. And Christian owes Billy enough that he's going to find it very hard to refuse.
