The series follows cash-strapped couple Gemma (Thalissa Teixeira) and Kieran (Gary Carr), after they decide to open their small apartment up to a third resident. Surprisingly, new resident Ray (Ariane Labed) seems to make things easier for the couple. She makes the apartment feel bigger, not smaller, and the extra pair of hands makes life easier. But they soon enter a polyamorous relationship and each resident finds themselves learning to navigate love and relationships in an entirely new way.
