Pulse (2010)

An emotionally unstable medical student gets in way over her head in the TV movie Pulse (2010). Hannah (Claire Foy) has been in a fragile state ever since her mother, also a doctor, died on the operating table a year ago. But now she's finally mustered up the courage to return to her studies, but while she was away some very sinister things have been brewing at the hospital where she and her ex-boyfriend Nick (Stephen Campbell Moore) work. But your blood will really be pumping when you get an eyeful of lovely blonde Emily Beecham's booblets in bed with her guy. Talk about a Pulse-pounder!
