Valerie's day starts off badly, when she oversleeps and ignores a cat's cry outside it's elderly owner's home, as she dashes off work. Jane, a social worker calls and finds her in a bad way and she's taken to hospital, where Valerie can't believe she could have done something to help her. Duffy ticks Alex off for being late for work but ends up with egg on her face, when she finds out the reason. She tried to save a man's life after having a working breakfast with a friend, trying to entice her to change careers. An ex-professional footballer has a drink problem and refuses to believe he's over the hill and expects his injury to take priority over other patients. Charlie's away and Valerie tells Duffy the budget for agency nurses has been frozen again and Jimmy's not happy with his new uniform. An elderly mother has to be admitted and it is Jimmy who sees the strange behaviour of the daughter and tries to get someone to check her, but fails, until she attacks her mother again.
