When asked what matters to her the most, Kate would, of course, say her children and her husband. Because she loves her life. Even when it involves making a costume late into the night, scouring the supermarket for the only bread rolls her children will eat and working during any spare moment in between. And she has found the way to hang onto her sanity in the process: Hours stolen away, once every few months, to have sex with another man. Until one such rendezvous when Kate turns on the television to discover that the very London hotel they’re in has been taken under siege. And with that, she knows that nothing will ever be the same. In the confines of a room with everything at stake, Kate is left to contemplate what has led her here, in hiding with a man who is not her husband while her beloved family waits at home.
