In Paris, two workers find a hidden chamber while digging the underground of the Saint Jean André Church. They collect the valuable objects in the spot but they are attacked by a creature. Meanwhile, the discredited Professor Jack Randall, who wrote a book about Gargoyles rejected by the experts, is encouraged by his friend Carol Beckham to peek the place out. They sneak in the site during the night and while Carol is collecting some artifacts, Jack is recording with his camera. Out of the blue, Jack sees a winged monster coming towards him and he flees from the location with Carol, but breaks his camera. They go to a bar and a huge stone falls over his car. Jack takes a cab to his boarding house and Carol is attacked and beheaded by a Gargoyle at her apartment. On the next morning, Jack identifies Carol's body and becomes the prime suspect of Inspector Gibert of several murders. Jack decides to seek out the reporter of a sensationalist newspaper, Nicole Ricard, and gives his tape to her cameraman Walsh. When Walsh recovers the badly shaped footage, he shows Nicole and they realize that Jack is not crazy and he had seen a Gargoyle indeed in the underground of the church. They decide to return to the church to investigate.

In the future humans have extended and improved our lives through highly sophisticated and expensive mechanical organs created by a company called "The Union". The dark side of these medical breakthroughs is that if you don't pay your bill, "The Union" sends its highly skilled repo men to take back its property... with no concern for your comfort or survival. Former soldier Remy is one of the best organ repo men in the business. But when he suffers a cardiac failure on the job, he awakens to find himself fitted with the company's top-of-the-line heart-replacement... as well as a hefty debt. But a side effect of the procedure is that his heart's no longer in the job. When he can't make the payments, The Union sends its toughest enforcer, Remy's former partner Jake, to track him down.

Three lives. Buffalo detective Lt. Cristofuoro, whose catatonic wife is in hospital, takes a special interest in Eric Komenko, a juvenile who killed his parents and will be freed on his 18th birthday. So has Lori Cranston, 15 or 16, her body fully developed and the object of lust by her boss and her mother's new boyfriend. She keeps a scrapbook about Eric, and when he's released from custody, she hides in the backseat of his car, insisting he take her with him on a trip toward Albany where he's planning to meet a girl. Cristofuoro is certain Eric will kill again, so he follows. It's clear early on that Cristofuoro's probably right, but what's Lori's motivation?
