Charlie Chaplin's "triple Trouble"

Triple Trouble (1918) is a short comedy film with Charlie Chaplin.
It was made after he left Essanay Studios, but they used old clips and extra scenes to make a new movie.

Charlie is a janitor (cleaning man).
He gets into funny trouble when he helps a scientist.
There’s a bomb, spies, and lots of silly chases.
Charlie tries to stop the bad guys.
But things go crazy — like always in his movies!
