In 1938, Dominic Matei (Tim Roth), a 70-year-old professor of linguistics, pining after the love of his youth, Laura (Alexandra Maria Lara), travels to Bucharest, the city where he and she met at university. Feeling that his fruitless search for the origin of human language has condemned him to a solitary, wasted life, Dominic is intent on committing suicide after this one last journey. However, while crossing the street, he is abruptly yet non-lethally struck by lightning. In hospital, Professor Stanciulescu (Bruno Ganz) informs Dominic that, much to both their surprises, the lighting appears to have regenerated him into a much younger man. Soon after, while residing at the Professor's home, Dominic also discovers that he possesses strange, psychic capacities.
