Everything in Lorna's life runs like clockwork, from her 6 a.m. morning run to the strict 60-minute counselling sessions she gives. It's the only way she can deal with the terrible secret she carries. When a new client arrives for his first appointment, Lorna feels her perfect life unravel in a matter of seconds. It's Andrew, the man she's spent the last year desperately trying to forget. It seems he can't forget her either... When Andrew is found dead in his home, grief quickly turns to fear when messages from him continue to arrive on Lorna's phone. Somebody knows her secret and wants to use it to destroy everything she has.
