Legacy (2008)

Synopsis: Popularity kills in this dark comedy centering on the murder of a geeky college freshman who was rushing the most popular sorority on campus. Lana Stevens (Haylie Duff) is president of Omega Kappa. Omega Kappa is the kind of sorority that most college freshman would kill to get in to. Unfortunately when a geeky rushee named Katie is found murdered during the biggest party of the year, it appears that Lana and her friends are willing to kill to keep it exclusive as well. Now the hottest girls on campus are the prime suspects in the murder case that has the whole student body talking. Are these mean girls really so protective of their popularity that they would resort to murder? As the investigation gets underway, an unhinged detective (Tom Green) determines to answer that question and ensure that justice is served.   Source: allmovie.com
