Real-time sitcom following the lives of a middle-aged couple during their first half-hour home from work. Roger is a botanist at the Winter Gardens and Val is a food technology teacher at a local school. With no children, the couple rely only on each other for distraction.
Val comes home to find Roger in an agitated state. She has left that evening's meal, a pack of fish fingers and some frozen peas, in his plant fridge in the conservatory. Thus begins a chain of rows, each one seemingly all about fish fingers.
Despite various attempts by both parties to smooth things over, there is a certain amount of tension in the air. It transpires that Roger is in a foul mood not because of the fish fingers, but because there are two new water voles at work who don't get on, and staff have named them after Roger and his boss Phil.
