Looking for a place to hang his hat, he ends up as a boarder in the quite WEIRD Beasley household, where Daddy Stanley, Mummy Marjorie & Baby Joyce reside & take him in as a family member (at first). Marjorie, a frumpy 50's something housewife, though very adept & conniving, is daily put off by the notion of sex with her sagging and slowly deteriorating husband. Thusly, Marjorie is searching for her lost youth so she hungrily and SHAMELESSLY pursues a fabulous affair with her handsome, love starved, young lodger, which triggers rages and MAJOR jealousy from her nubile, prepubescent budding baby daughter, Joyce, of whom also has a crush on Guppy & gives her virginity to him .
This ACTUALLY leads to a really freaky lust triangle. The insatiable Marjorie can't get enough sex from poor Mr. Guppy, gets jealous of her daughter and thus the movie has quite an eye-opening shocker of a finale... The TRUTH, my friends, IS STRANGER than FICTION!!!
