In Between (2012)

Doctor William Dyer may be the smartest theoretical physicist alive, but he has just blown it. After a routine CERN experiment goes horribly wrong, Dyer has to get to the emergency data access facility he has installed in an abandoned building nearby. A race against time to avoid unthinkable Armageddon turns into something else - a struggle with himself and his own guilt. Only now, he’s not alone.
