He’s waiting for Dorothy, his fiancée, and tonight is the last night they’ll be meeting here, for it’s May 31st, and June 1st marks their wedding day. But she’s late, and Johnny soon learns of a horrible accident—an accident involving a group of drunken men, a low-flying charter plane, and an empty liquor bottle. In one short moment Johnny loses all that matters to him and his life is shattered. He vows to take from these men exactly what they took from him. After years of planning, Johnny begins his quest for revenge, and on May 31st of each year—always on May 31st—wives, lovers, and daughters are suddenly no longer safe.

    Al Colby, an American expatriate working as a private investigator in Mexico City, is contacted by an old acquaintance in Los Angeles who hands him a cold case involving a missing person. Robert Parker’s mysterious disappearance is tying up a family fortune and is enraging his abandoned wife who can’t tap the family coffers without proof of death. The case sounded routine enough, right up his alley, but the trail for the missing Mr. Parker leads Colby down a rabbit hole winding through a number of South American countries, each one a dead end. Running out of funds and clean shirts, Colby is ready to throw in the towel, but the stakes are too high and his client fuels the search with additional cash. The deeper Colby digs the more entangled he becomes in a decades old mystery of misplaced loyalties, family secrets and riches in nitrate ore. In between tequila shots and beautiful women, Al Colby has a case that drags him in deeper with each step.  But can he piece it all together before the quicksand swallows him whole?
