Sad-sack dumped wife Susan (Stephanie Swift) drops by pal Michelle Michaels' house to hang out with her and hubby Evan Stone for a couple of days, and to buoy up her spirits. Michaels gives her a make-up makeover and - surprise! - she looks like Porn Star Stephanie Swift. Susan finds this mistaken-identity thing liberating, first imagining herself an observer on a scene with Randy Spears and Anna Mills, taking a jizzload to the kisser before Mills turns into Michaels and wakes her up with a start. She then drops to her knees to pleasure wide-eyed video store clerk Alex Sanders, who thinks she's you-know-who, and later gives blowjob lessons to Chloe Dior on Evan Stone's rigid member in an elevator before finally falling completely into the role advising a neophyte porn director how to shoot a four-, no, five-way orgy before going face to face with the real Swift for her comeuppance.

Excellent sex scenes (seven, not all complete) in service of a very clever premise, which gets better the closer one is to the porn industry, with in-jokes and surprise cameos adding to the fun. Fine special effects in the Swift-confronts-Swift sequences will not disappoint, and music and well-shot and well-lit images add value as well.
