One Small Indiscretion (2017)

Years ago, heartbroken and officially separated from her husband, Caroline briefly turned to the arms of another man. It was only one small indiscretion – a brief affair, forgotten after she and her husband reunited. But beautiful Elle, daughter of Caroline’s lover, hasn’t forgotten. She rents a guesthouse from Caroline, her husband, and teenage son with one purpose: to destroy their lives the way Elle thinks Caroline destroyed hers.
