Living in the titular* sorority house, seven student girls decide to have themselves a party to celebrate their graduation. Only house mother Mrs. Slater (a blatant Mama Voorhees wannabe) is proves to be a right grumpy-pants and storms about the house, bursting the girls’ water-beds and shouting a lot. The girls decide to teach Slater a lesson, pulling a prank on the poor biddy. When said prank involves a gun and a swimming pool, you know it’s all gonna end in tears. Unfortunately, their accidental murder happens to coincide with the party they had planned. Can't cancel the band. The booze has already been bought. Sink the dead body; there's a party to be had.
The House on Sorority Row is about as derivative as 1980s’ slasher movies can get. Every cliche imaginable is in there, accompanied by a few more for good measure. You'll be able to predict who gets killed when and where, and you'll even know when to expect the fake-out shocks. The fake-out shocks, in fact, are usually followed by fakey-looking deaths, complete with blood several shades too red, and plastic-looking limbs.
* Tee-hee. Tit. Tits feature quite heavily in this movie and this review.
