It's been years since Stanley Ahearn lost interest in staying alive. Every Friday night, he pays a visit to San Francisco's Tenderloin District, where pleasures are simple and cheap. One night he shares an otherwise deserted bar with a green-eyed woman. Three days later, he wakes to find himself in a sleeping bag, missing a kidney and with something fatally wrong with the one that's left. So Stanley finds a new perspective. If he wants revenge, he has to find the woman with the green eyes. If he wants to live, he has to find a new kidney.
