The movie is Action/Horror. I am a fan of Millenium the TV series so many of the ideas in this are Milleniumistic.
Alright, here is the pitch.
Florida 2005, hurricane Katrina rages against the west Floridian coast, an FBI agent Emily Beckerman stumbles across an experiment. A mysterious man Jacque Reim studies a serial killer in a beach house. After a cryptic conversation, Beckerman extinguishes both Reim and the experiment with some violence.
Two years later Jacques Reim is spotted by the security cameras at Dubln airport. Contemporaneously, a girl is kidnapped and her boyfriend slaughtered in the perpetually gloomy city of Cork, Ireland. On the wall of the crime scene is a cryptic message. Beckerman aids the irish authorities in their pursuit of the killer.
