When Kate (Jeannine Kaspar) and her younger sister Liz (Kseniya Pinch) are reunited on a Mediterranean Island, Kate meets Myrianthy (Marianna Rosset) and a group of locals and agrees to an exciting ride on a hot air balloon. But the joyride takes a dangerous turn when it becomes untethered and the passengers ascend without a pilot. Their cell phones out of range, and the balloon running out of gas, Kate and Myrianthy begin a desperate fight for their lives as the balloon is pushed out over the open ocean. Back on land, Liz has become an unwanted "material witness" to a robbery committed by Jack (William Baldwin) who happens to be Myrianthy’s boyfriend! Matters then take a dramatic twist, one that will mark their lives forever. While Liz may be their only hope of rescue, can she get to them in time?
