A disgraced but kind-hearted fertility doctor, Dr. William Han (Paul Sun-Hyung Lee), embarks on a breakthrough clinical trial in which four women give birth to kittens! The cat-pregnancies must remain secret for the duration of the trial. But when Dr. Theresa Mackenzie (Helene Robbie), walks back into Dr. Han’s life and joins the clinical team of the trial, everything is threatened. Her jealous ex-husband (Drew Nelson) stalks the clinic, hell-bent on exposing the trial and ruining Dr. Han’s life… again. Now Dr. Han must open up about his past, come clean about his feelings for Theresa and enlist the help of his four kitty-mammas if he wants to bring the world’s first truly hypo-allergenic cats into the word.
