Tara is a professor and studies human relations. She has developed a method that improves the odds of determining whether a potential partner is "the one". At a lecture, she is challenged by Ryan, who is there with his girlfriend. He questions why Tara didn't test the method herself. The issue spreads on social networks and Tara suddenly has a publicity crisis to deal with. The university suggests that she take the test for the sake of it. To show his girlfriend, who has broken up with him, that he has such a side, Ryan takes part in the experiment.
It is a good romantic film, even if her theories would have a hard time coping in the research world.
