It is written and directed by The Cowboys author Dale Jennings and narrated by F-Troop and Fractured Fairy Tales star Edward Everett Horton.

In the film, ten children, nine of whom have monkey faces, hats and tails, plan on going to the park for a picnic.

After experiencing a mild revival of popularity on the Internet, the film was presented as a RiffTrax feature in April 2008, with commentary by Michael J. Nelson, Bill Corbett, and Kevin Murphy; they described the film as a "concentrated dose of lab-purified nightmare fuel" and said that it makes monkeys more terrifying than they already are.

[7] Footage from the film is used in several music videos, such as "Bloody Palms" by Phantogram[8] electronic rock band, "Fool's Life" by Dr. Dog,[9] "St. Peter" by Black Spiders,[10] "January" by Venetian Snares,[11] "Oh, Me; Oh, My" by Nerf Herder,[12] and "Condotta, Condottiere" by Mauk Tenieb.

The film has probably reached its largest audience via its use in fan-made YouTube music videos for "Everything You Do Is a Balloon" by Boards of Canada[16] and "I'm the Devil" by Clams Casino.
