Nine hundred children are sent home from school and thousands inoculated during an outbreak in Massachusetts that depletes local supplies of antibiotics and lands four middle school students in the hospital.

Ten-year-old Kayla St. Pierre spends ten days in critical care and loses all of her fingers and both legs to the disease.

Scientists trace the disease to members of the Girls Club sharing lip gloss on a bus ride to see Disney on Ice, an excursion that exposes thousands of students from 19 schools to an aggressive strain of meningococcal meningitis.
