Minor Details (2009)

Someone's trying to make the students sick at upscale boarding school Danforth Academy. Abby, Paige, Claire, and Taylor join forces to solve the mystery. Could it be Mia or Riley--the girls who have everything that money can buy? Or Emily, the Principal's know-it-all daughter? Maybe it's wacky Sean Meneskie? Or the school's strange Professor Plume. Whoever it is, the four best friends will find out.
