Pulse

A year earlier medical student Hannah Carter (Claire Foy) freaked out in the operating theatre when her doctor mother, a cancer patient, died. Now she is back to resume her studies amongst whispers of her instability.
Why does the stomach of Charlie Maddox, a man who has had five operations for abdominal cancer, undulate when she feels it? How come the cut on the hand of surgeon Nick Gates (Stephen Campbell-Moore), Hannah’s ex-boyfriend, never heals and why is Nick secretly injecting Charlie but not recording it on his notes?
Hannah decides to investigate, uncovering a secret involving a new wonder drug with potentially lethal results.
