In a small Alpine village, a group of men, women and children is in a state of confusion as they try to return to their homes after years of being away. What they don't know is that no one is expecting their arrival because they have been dead for several years. Upon returning, they realize that their friends and family have moved on to the next stages of their lives since the now-returning souls passed on. Coinciding with their reappearance is a series of murders that bears a chilling resemblance to those of a serial killer from the past.
As the movie begins, a slow moving mostly gray haired crowd walk through a French town. These people are clean, combed, and casually dressed. Integration with society becomes the first issue that concerns the town politics. While the authorities monitor and record movements, habits, sociability, and intelligence the personal relationships between the returned and their respective live spouses and parents comes into the foreground. Painful memories are awakened, guilt, fear, love, even unearthed passions are aroused. However, monitoring the returnees shows them to be very much apart from their live cohabitants and in fact involved in late night clandestine meetings, seemingly plotting with more intelligence than they are exhibiting in their day jobs.
