Kylie Ireland is such a hottie in this that you'll be willing to forgive the silly plot.  She plays a private eye who gets sucked into a tale of intrigue involving an old immortality spell crafted by the wizard Merlin.  Peter North and Missy are the villains.

Ireland kicks things off with a hot one-on-one with Scott Styles, then works her way through some girl/girl action with Missy, capping it off by giving Tony Tedeschi and T.T. Boy a run for their money.  Peter North clocks in by drilling AlexXx Knight and Crayola Blue, and later engaging in some quasi-mystic pole vaulting with Missy.

But Ireland is definitely the star here, a hard-boiled detective who always gets her man (or woman), and never stops having a good time.  Even when the bad guys tie her up and start fucking, it's clear she's enjoying herself.  Very good stuff.
