After his brother Luke is accused of being involved in a rash of thefts at the school, Emmett must find a way to prove his innocence before their parents ship Luke off to a school in Maine. Emmett enlists the help of his sixty-something SAT tutor, Mary, to solve the crime. Together, with the assistance of his oddball friends and a benevolent science teacher, Emmett and Mary prove Luke’s innocence and discover the real culprit may be someone from Mary’s past.
