A Harvard University student finds a strange letter that seems to be signed by George Washington. When trying to contact an expert (Prof. Chandler) to authenticate it, he is murdered but the letter disappears. Then Chandler, who does not know anything about the case, gets chased by the mafia and haunted by a TV reporter (Polly Bishop).
Unfortunately the movie Dirty Tricks is not yet available on HBO Max.
