Dr Steven J. Fisher is a young and brilliant biochemist (special subject: the female orgasm). He's invented a Viagra-like pill for women - now he just needs his results to be perfect. Annie is an orgasmically-challenged arts student (special subject: Victorian semicolons). She's just volunteered to be one of Fisher's case studies - but for some reason his miracle treatment isn't working. As scientist and subject bond over romantic meals lit by the flickering glow of a Bunsen burner, Dr Fisher is surprised to find his feelings taking a most unscientifc turn...what if love is one thing science can't explain?
