In February 2010, Angela Spencer received a heart transplant after years of battling an unknown heart disease. Months after the operation, she wrote a letter to the donor's family where her new heart came from. The letter was returned. Six years later, Jerimy Sherin, Egan Galvin and Luke Spencer began a search to find the family of Luke's mother's heart donor. Filmed in real time, from family interviews to researching the organ donation process, Heartsick is a documentary about how the gift of new life changes more than one.
