A dramatic-comedy, inspired by the lives of two people with Asperger's Syndrome, a form of autism, whose emotional dysfunctions threaten to sabotage their budding romance. Donald is a good-natured but hapless taxi driver with a love of birds and a superhuman knack for numbers. Like many people with AS, he likes patterns and routines. But when the beautiful but complicated Isabel joins the autism support group he leads, his life - and his heart - are turned upside down.
