Roy Milano, a self-described movie detective who is devoted to finding, hoarding, and reciting arcane information about films, once again stumbles into a murder case—this one centering on a copy of Jerry Lewis' infamous unfinished film, The Day the Clown Cried, shot in Sweden in 1972. Though rough cuts were apparently screened for the filmmaker's colleagues and Hollywood insiders, the movie was quickly suppressed and never exhibited to the general public or to any critic or film historian. And now certain cinema buffs are ready to kill to possess that elusive footage. It's up to Roy to save the day, and the film, before everything unravels.
