ACAPULCO G.P.O. Acapulco is a paradise to some, but for most of the expatriates living here, the good life is a mixed blessing. Too much money and too much temptation is a bad breeding ground. Jim Harris knows that all too well. As a painter, his glory days are behind him, and all he can do is teach. His wife Sonia has become the breadwinner, modeling in the nude for the other painters. So Jim and Sonia argue-and drink. But now Sally, a teenage girl Harris teaches, has gone missing, and he is the last person to see her. Harris knows he was drunk last night, but he's sure he didn't rape and murder his young student. He wasn't that drunk. So why do they find one of his pallet knives, sharpened to a deadly point, near a pile of Sally's clothes?
