The Lost Son

Xavier, a French private detective in London, is asked to find the missing 30-year old son of a wealthy elderly couple. His investigation takes him on a journey into the darkest parts of both the city and his own soul. He finds the seaside hotel where the missing Leon has been, but now there is only his girlfriend Emily and a young boy she is looking after. But there is also a videotape that reveals to Xavier that Leon's flight might be from more than just drug debts.
