Suzy's a soldier, born and bred, but fitting back into civilian life after being on tour in Iraq isn't easy. On arriving home to a hero's welcome, it's clear from the moment she sets foot in her house that something's not right. After Suzy and a fellow soldier, Paul, took part in a hearts and minds mission that resulted in the death of a child, she's unable to escape the immense weight of the guilt on her shoulders. Once at home, Suzy is haunted by the memory of the Iraqi girl and becomes obsessively protective of her own child, perceiving threats where there seem to be none... As Suzy's paranoia builds, her behaviour becomes more and more erratic, until finally, she puts her own child in serious danger.
