Some story ideas, perhaps thrown around at a Writers Room, are best left crumpled up and thrown into the wastebasket. But the policy at Pure Taboo is clearly "waste not, want not", so this Penicio Del Toro screenplay was actually shot and released, despite its obvious shortcomings.
Seth Gamble arrives home, shouting out for his wife Nancy and daughter Mara. Instead, he's greeted by cutie Tracy (ever-young looking Jane Wilde (at 25 still a believable teen character) claiming to be his daughter, as amplified by mom Nancy (Charlie Forde).
This seeming bit of gaslighting is quickly resolved: Forde tells him she's discovered his affection for stepdaughter porn via his computer, so she simply traded his real-life offspring Mara for Tracy, whose family dug the switch. Seth can't contact his real daughter and boy, is he angry.
But not angry enough to storm out of the house -instead he flees to his bedroom, and the women decide to try very hard to get him to agree to the kinky role-playing they have in mind.
This nonsensical premise seems dead in the water, but directors Siouxsie Q and Michael Vegas go full steam ahead: Jane has little trouble seducing "daddy" and soon Charlie joins them for a threesome, all of them enjoying it immensely.
