This movie alternately called "Pinball Summer" or "Pick-up Summer" (since the pinball craze had long since ended by the time it hit American drive-ins) is basically a Canadian version of the 1970's American teen exploitation (or "sexploitation") drive-in flicks, which means that despite the thick Canadian accents it is virtually indistinguishable from contemporary American teen comedies like "The Pom-Pom Girls", "The Van", "Malibu Beach" and so forth. There is no real plot, for instance, just a lot pranks and zany hijinks revolving around a pinball tournament and a trophy that keeps getting lost or stolen. The male protagonists are two over-aged high school students who are much more obnoxious and somewhat less funny than actual teenagers. Their enemies are a sorry motorcycle gang who look like north-of-the border rejects from "Grease" or the Frankie and Annette beach movies, and a snooty rich couple who the protagonists seem to torment for no other reason than because they're rich and snooty.
Of course, the main reason to see any of these movies is the girls. The two protagonists are chasing around two sisters played by a couple of very attractive actresses (Karin Stephens and Helene Udy). The two wear various outfits that are never more than ridiculously skimpy, but have only very brief nude scenes. Most of the nudity is provided by the voluptuous Joy Boushel, who later became a minor Canadian scream queen appearing in "Humongous" and "The Fly". She leaves an indelible impression of boobs and freckles here, especially in the big "strip pinball" scene. Unfortunately, her character "Sally" also has her own theme song ("Sally Joy/you ain't no boy. . ."). Which brings me to the music: imagine the worst kind of sappy music from the late 1970's--now imagine something much, much worse and you're starting to get an idea of the godawful soundtrack to this movie.
So all things considered would I recommend this? Well, it could have used a little more nudity and a LOT less music, but it's really no worse than the American teen movies of the time, so if you like those. . . And the director, George Mihalka, would go on to make one of the better Canadian "slash-for-cash" horror movies "My Bloody Valentine" (if only some psycho in a miner's helmet would have put all the male hosers in THIS movie out of my misery, but oh well. . .).
