Alison gives the Ghosts the biggest telling off of their lives (deaths) and they are determined to find a way to show her how sorry they are.
Mary, however, refuses to take the blame for something she didn’t do, as that didn’t work out so well for her last time.
Mike notices how stressed Alison has been lately and, prompted by a last-minute cancellation by guests, decides to treat her to the most relaxing day off ever. But they soon find that trying to relax is a deceptively stressful endeavour.
Ghosts – Friday at 8.30pm on BBC One.
