Evoking a lighthearted and clever tone, Proof of Love is a romantic comedy about a charmingly neurotic Harvard graduate student, Samantha, whose life doesn’t seem to be working out the way she planned. Frustrated by life’s unpredictability and determined to apply scientific principles to her love life, Samantha sets off on a series of wild dating adventures – a journey that ultimately leads to her understanding that nothing can be controlled and that life is indeed more about the ride than the destination.
