Accomplished chef Gemma and her paramedic boyfriend Kieran live together in west London above Gemma’s cafe. Kieran and Gemma are madly in love. But, unfortunately, love alone can’t pay cafe suppliers or London rent. The pair are barely making ends meet, and their different shift patterns mean they are like ships in the night.

To ease some financial pressure, they decide to take in a lodger. Enter Ray, a former world-class synchronised swimmer, whose arrival with a Volvo full of baggage commences a modern-day love story that changes the trio’s lives - and how they view relationships - forever.
