A warm, intimate comedy-drama about three people discovering that unconventional domestic arrangements can be genuinely nurturing and joyful.

In crowded and expensive London, cash-strapped couple Gemma and Kieran open their small apartment to a third person. Somehow, their new addition, Ray, makes the flat seem bigger, not smaller. Gradually, many things become easier, nicer and better with an extra pair of hands.
