Afghanistan, 2007. Carl meets Sarah, a nurse, at Camp Bastion and they feel an instant connection. But she's the girlfriend of his fellow soldier, Danny, so he pledges to keep his distance. Finally back in England, Carl vows to never forget those who didn't make it home, honouring each of them with a tattoo of a poppy. While many miles away, Sarah tries to forget the man she swore to leave behind. But when Carl and Sarah are thrown back together, it's clear that both of them are broken. But do the scars of what they went through run to deep, or is there a chance they can find happiness again, together . . .
