Set in present-day Liverpool, twentysomethings Elliot and Jess are best friends united by a bond of grief at losing Peter - the first and only love of Elliot and Jess's twin brother.

It's been five years since Peter went missing in mysterious circumstances, and still reeling from the trauma, the best friends spiral into a hedonistic lifestyle, partying to numb their grief while clinging to a small hope that they will one day find out what happened. When Elliot meets Will, he starts to think he can put the past behind him. But when Elliot learns Will has his own dark secrets, just as Jess is contacted by somebody claiming to be her brother, it sets into motion a determination for the pair to find out if Elliot's romantically cursed - or being targeted.
