In the throes of a stifling summer heatwave, a brother and sister, both single and restless, find solace in each other's company. Their games of cards and board games soon escalate into a charged game of truth or dare. Boldly, the sister dares her brother to touch her, to make her feel alive. He hesitates, then tentatively reaches out, his fingers brushing against her bare, tanned skin. She responds in kind, her touch electric on his chest, her eyes locked onto his. Their bodies sway closer, breaths shallow, as they succumb to the forbidden fruit of their shared desire.
