Seventeen-year-old Henry Page (Austin Abrams) has never been enamored. He likes himself a sentimental, however the sort of once in a blue moon love he's been seeking after simply hasn't occurred at this point. At that point, on the principal day of senior year, he meets student from another school Grace Town (Lili Reinhart) and it appears to be all that is going to change. At the point when Grace and Henry are picked to co-alter the school paper, he is quickly attracted to the secretive newcomer. As he learns the terrible mystery that has transformed her, he ends up going gaga for her - or possibly the individual he thinks she is.
