Providence

Exposure (3x17)

:

After Syd greets her old medical school pal on leave from a rural African hospital, he shows frightening symptoms of the super-deadly Ebola virus, forcing the health department to clamp a quarantine around her clinic -- as well as the Hansen household where Joanie is hosting a chaotic children's birthday party. In the meantime, while a desperate Robbie spots his family on the TV news and heads home hoping to help, Joanie discovers that his girlfriend -- who's also trapped inside the house -- was the same girl who tormented her at summer camp years before. Elsewhere, Jim busies himself treating a bulky bulldog suffering from serious anemia.
