PC Joe Penhale has an unexpected visitor in the shape of his ex-wife Maggie, who appears to have completely forgotten that they split up a couple of years ago. Joe takes her to Large's restaurant, where fellow diner Martin quickly spots that Maggie is showing symptoms of amnesia. Louisa's mother Eleanor catches up with her old school friend Paul, a local fisherman, who takes her out on a date.
In an effort to get Maggie to stay in Portwenn after she gets the all-clear, PC Joe Penhale tries to prove that he is the man for her - and even engineers situations where he can show off his macho side to impress her. But will his attempts at subterfuge work? Martin steps in when school caretaker Mr Coley becomes muddled and puts the children of the school at risk. Also, tensions mount between Martin and Louisa.
