Lucille Marsh finds herself at Haverford Memorial, a highly praised all-girls school known for their strict disciplinary measures, at the hands of her parents who hope the school will straighten her up. Tensions rise when she meets Harry, an upperclassman from Haverford's neighbor and rival, Cardigan Academy, and Lucille is once again in trouble, this time for something she believes is untrue. With the help of Harry, who she still does not trust, and her best friend Marie, Lucille must prove her innocence before the clock runs out and she is sent back home.
