Lilly Hall, a Canadian-American teen, has always been curious about her stepfather, Ike Diezel, but she never expected to act on her feelings. One hot summer day, she finds herself alone with him in their shared bathroom. As she undresses, her stepdad walks in, apologizing but not leaving. Lilly, feeling a rush of adrenaline, decides to tease him, putting on a show as she washes herself. Ike, initially shocked, can't help but watch his stepdaughter's provocative display. When Lilly turns to him, their eyes meet, and the tension becomes palpable. She bites her lip, and Ike, unable to resist, steps closer, ready to give in to their taboo desires.
