Reese Robbins and Tyler Cruise, bound by blood but separated by age, find themselves in a tangled web of curiosity and forbidden desire. Their late-night games of truth or dare take a taboo turn when Reese, emboldened by alcohol, dares Tyler to touch her breasts. Tyler, hesitant but hungry, tentatively cups Reese's perky mounds, igniting a spark that neither can ignore. Their stepmother, Sophia Locke, unwittingly bears witness to their secret, their naughty games of dare evolving into a full-blown family fantasy.
