Kate stretches her legs and turns on the TV while James washes away the traces of their morning. She watches in horror at the unfolding news: the hotel they are staying in has been taken under siege.

She should be making her way home, working on appearing normal, getting ready to re-enter family life with her loving husband Vic and their two adored children. Instead, she is trapped somewhere she shouldn't be, with a man she definitely doesn't love.

How will she begin to tell Vic what she is doing here? If her body is found, will it give up the secret of what she's been up to? She's been so careful hiding the evidence of her affair: write nothing down, leave no trace. Will he begin to understand why?
