Rachel is a single mother of two who obsesses over accident reports, parenting tips and ensuring her children are safe. It is out of character for her to pull over and help a man and his daughter change their flat tire. Len is the widowed father of Olivia. Surprising herself further, Rachel agrees to a date with Len. As they continue to date, Rachel's children are horrified to find out that Len's daughter Olivia is the ' Inside Out Girl" who attends their school. Olivia has non verbal learning disorder. Although very bright, she is unable to process facial and voice cues, resulting in socially inappropriate behaviour and anxiety. She often chooses to wear her clothes inside out, thus the name. She is extremely well informed about rats, frequently quoting rat facts in times of stress. As she falls in love with Len, Rachel is forced to face some issues from her own past. Her children are also going through difficulties that she is unaware of. Could this relationship really work?
