Ten years ago, Ryan Comeaux was convicted of killing his girlfriend and was sentenced to life in prison. Now a witness has come forward who claims she was with Ryan the entire night and it's not possible that he was the killer. But the local police assume she's mistaken and aren't interested in reopening what they view as an open-and-shut case.

The witness, Kelsey Spalding, has her own reasons for wanting Ryan's conviction overturned and hires Swamp Team 3 to prove him innocent. Fortune has solved cold cases before, but never one with so little evidence and so many suspects with not only strong motive but opportunity. Can she solve a decade-old murder, or will the real killer strike again to cover his tracks?
