According to IMDb, "In lawless storm ravaged New Orleans, beleaguered Detective Sean Riley is trying to cope with the death of his young son and the abandonment of his wife. Facing a probable suspension from the department, Riley is teamed with a young homicide Detective, Will Ganz, to help solve a series of brutal murders that have plunged the city into a major gang war. The two quickly realize there is something far more sinister going on than either could have ever imagined."
Blalock plays a character named Stacy (you can see her a couple times in the trailer below). The movie is still working on a distribution deal, so it is supposed to be released in early 2010.
