Don Tillman is a scientist through and through. Everything he does is measured, calculated and precise. He isn’t particularly successful with relationships as a result and so decides to set up The Wife Project. A questionnaire is compiled to evaluate applicants as potential wife material for Don. Only the best will do; they must fit some very stringent requirements to even be considered for a date. One day Rosie appears at his door. She is completely not Wife material – she smokes, is disorganised and nothing like Don at all.
