Katie (Thorne) is a 17-year-old who needs to remain inside the entryways because of an uncommon sickness. The scarcest introduction to the daylight can mean her demise. An ordinary life is not in it until the point when she meets Charlie (Schwarzenegger). They enter a sentimental summer, where they can just appreciate around evening time or inside. Riggle will play Katie’s dad, Jack, a forgiving man who does everything for giving his little girl a decent life.
