Porky doesn't have enough money to buy an ice cream soda. He sits on the curb sulking, while a passerby drops his cane. Porky picks up the cane and hands it to the man, and is pleasantly surprised when the man gives him a coin for a tip. He excitedly runs around town picking up dropped items for people and collecting coins from them. Meanwhile, a mad bomber on the run from the police leaves a bomb that looks like an ordinary alarm clock in front of a building. Of course, Porky sees this, but doesn't know it's a bomb, so he picks it up and tries to return it to the man. The bomber runs from the bomb, but Porky follows him throughout the city, until the bomber accidentally runs right into the back of a paddy wagon.
This short is considered the first solo Porky Pig short.
Author Thomas Pynchon refers to the cartoon involving "Porky Pig and the anarchist" several times in his novels The Crying of Lot 49 (Vintage, 2000, p. 63) and Gravity's Rainbow.
The short marks the first use of the premise of a person tracking someone and is always waiting for that other person wherever he turns up, which would later be expanded and exaggerated by director Tex Avery in the Bugs Bunny/Cecil Turtle short "Tortoise Beats Hare" (1941) five years later, as well as the Droopy cartoon "Dumb-Hounded" over at rival studio MGM seven years later. This premise would also be exaggerated by Bob Clampett in the Daffy Duck short "Draftee Daffy" (1945) nine years later (co-incidentally Bob Clampett also worked as an animator on this short).
