SEAN's getting married soon, so he and 4 friends are heading out of the city on a stag weekend. There's his quiet younger brother GEORGE who secretly loves Sean's fiancé, his macho, philandering best man TED, his nerdy work colleague HAMISH, and his snooty soon to be father-in-law HARROLD. Sean wants it to be a more civilized event than the stripper-filled, booze-fueled norm, so he's rented a little cottage on the outskirts of an old abandoned logging town where they plan on spending the weekend fishing and hunting.
But best man Ted soon becomes bored of all this 'outdoorsy, male-bonding crap', and when he spots a phone number scratched onto the cottage long drop wall with the slogan "looking for a good time", he decides to call it. That night, much to Ted and the others' surprise, a beautiful woman arrives at the cottage proclaiming herself as the evening's entertainment. A drunk Sean, ignoring the advice of the other men, is convinced by Ted into taking a private dance from the woman. But the private dance quickly escalates further, and as the woman unbuttons Sean's pants she begins to suck, suck, suck... the life and all the blood out of Sean.
The woman Ted hired isn't a stripper, but instead an evil blood thirsty creature. To make matters worse, the woods surrounding the cottage are crawling with other similar creatures; beautiful, evil women who once literally sucked this logging town and it's men dry. Vampires? Succubus? Who knows!? All the remaining men care about is survival, and for that they must band together and fight off arousal anyway possible. Be it Ted's excessive drinking, Harold's age appropriate impotence, Hamish's thoughtful approach of self-castration, or George's honest, faithful, love for his just-dead brother's fiancé. No arousal by sunrise, equals survival.
