This documentary follows a string of events - in particular, a tragic death of Keira Ball in a car accident at the age of 9, and Max Johnson, aged 8, who received Keira's heart to replace his own diseased heart - that eventually lead to a new organ donation law in England known as "Max and Keira's Law".
