Pathé film number 380, released as "What Happened to the Inquisitive Janitor" in the US and as "Peeping Tom" in the UK. The title "What is Seen Through a Keyhole" was given 'a posteriori' and should not be regarded as its original. As a janitor is cleaning a hotel, he decides to peek through the keyholes to observe some of the guests in their rooms. In room 8, a woman is busy making herself look more attractive, and the janitor enjoys watching her. There are also some interesting things going on in the other rooms on the floor.
