Vincent Poirel, a multinational executive, has won the contract to build an Olympic stadium. The original design, however, was by young architect Simon Variot. When he discovers it, he goes to the construction site and is run over by Poirel. Simon dies, but is resurrected in the body of Poirel's son, who doesn't understand why the little boy hates him so much.
