Portia has overcome a lot in life. Born with Down syndrome, Portia has been through many surgeries, lots of doctor's appointments, and strange looks from people who want to limit what she can do. Inside herself, Portia knows she can do anything--including getting over her fear of dogs. But when Penny shows up at Portia's house, she isn't so sure.
