Having returned to life, the living dead now co-habitate with the living. One morning, a small French city wakes up to discover groups of recently dead people walking into town. No one knows the cause and there's no time to find out. After tearful and sometimes strained reunions, the returnees look to resume their old lives. But their jobs have been filled, widowed partners have moved on, and Social Services struggles to cope with their various needs. And, also, though healthy and energetic, the returnees seem somehow different from before.
