our undertakers in financial trouble latch onto a one-off opportunity to change their lives and bid farewell to a profession they entered for a while, but got stuck in for good. On the promise of a large fee, they fulfill the dying wish of a rich Greek who lived his life abroad: he wants them to take his body from Athens to a village in Boeotia for burial...on foot. Deciding to grant his bizarre request, they embark on an odyssey, which soon becomes an unexpected voyage of discovery.
