A fireside conversation between two lovers, Jamie Gillis and Delania Raffino, and the suggestion of a trip to Lake Shasta prompts the latter of the pair to recount a story from times past, when she last visited the lake with her ex-husband and Senator, Jack Wrangler. Of course, the trip was anything but typical, as it involved all manner of horny high-jinks, two of the participants--including Raffino herself--getting seriously lost, an assortment of awkward moments and interactions, and...finally...a trio of "protestors" intent on taking hostages and raping members of the party. This outlandish, fictitious trip is the primary focus of the film "Summer in Heat", an overall-good, 1979 release from VCX and director Alex DeRenzy.
