An impromptu goodbye party for a professor turns into an interrogation when he reveals he's actually an immortal who has walked the planet for 14,000 years. When professor John Oldman (David Lee Smith) suddenly resigns his post and announces he's moving away, his colleagues turn up for a farewell party. Pressing him for an explanation for his departure, he finally reveals to his astonished guests that he is in fact a 'man' from the Upper Paleolithic era who has survived to the present day. As his colleagues, a biologist, a Christian literalist, an anthropologist and a historian, attempt to shoot holes in his proposal, professor Oldman relates his remarkable story and the famous encounters he has had with the likes of Van Gogh, Buddha and Christ.
