In the heart of a seemingly ordinary home, a hidden camera captures the unassuming Dodge family's dark secret. The siblings, left alone, begin to act out their forbidden desires. The eldest sister, her heart pounding, tentatively reaches out to touch her brother's arm, trailing her fingers down to his hand. He responds, his breath hitching, as she guides his hand to her thigh, slowly inching it up her skirt. Their eyes meet, a silent agreement passing between them. They're playing with fire, but the thrill of the taboo is too enticing to resist.
