David Grant (Tom Broadwell), a 25-year-old man from Great Britain, has a PhD in Mathematics and a Masters in Human Development & Psychology from Harvard University. He has come to Montreal and bought a whole commercial building that has lofts. His goal is to find the love of his life. This is why he kidnaps Francesca Besson (Caroline Brassard), a 24-year-old sales executive, because on paper, she has a 99,3% compatibility match (based on the personality) with him. Will David, with the help of his "science", manage to make Francesca fall for him by keeping her against her will in a loft with windows sealed by a wood panels? Or will Francesca manage to escape?
