Plot.
The cartoon starts off with a devious spider (voiced by Jack Mercer) who holds many fly captives in the rooms of "The Cobweb Hotel" and sees a newly married couple of flies booking a room into the fake hotel. After they become separated, the male fly fights with the spider being a "flyweight champion". However, he still becomes stuck in a net during the match.
Meanwhile, his wife wriggles herself free from the web and gives freedom to all the captives, who torment the spider by flicking several sharp pen heads and firing many aspirin pills at the spider. After paying revenge to the spider, the couple attend another wedding ceremony, followed by the other captives of the hotel, until the ending scene rolls in.
