Trigonometry

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

Accomplished chef, Gemma (Thalissa Teixeira), and her paramedic boyfriend, Kieran (Gary Carr), live together in West London, above Gemma’s café. Kieran and Gemma are madly in love. But unfortunately, love alone can’t pay café suppliers, or London rent. The pair are barely making ends meet, and their different shift patterns mean they’re like ships in the night. To ease some financial pressure, they’ve decided to take in a lodger. Enter Ray (Ariane Labed), a former world-class synchronised swimmer, whose arrival with a Volvo full of baggage commences a modern-day love story that will change the trio’s lives - and how they view relationships - forever.
