A short film depicting the execution of Mary, Queen of the Scots. Mary is brought to the execution block and made to kneel down with her neck over it. The executioner lifts his axe ready to bring it down. After that frame Mary has been replaced by a dummy. The axe comes down and severs the head of the dummy from the body. The executioner picks up the head and shows it around for everyone else to see. One of the first camera tricks to be used in a movie.
