After the Jigsaw Killer becomes bedridden, his apprentice Amanda (Shawnee Smith) kidnaps Dr. Lynn Denlon (Bahar Soomekh) and forces her to perform a lifesaving surgery on him. While Dr. Denlon tries to keep the Jigsaw Killer alive, Kramer forces his latest victim, Jeff (Angus Macfadyen) — whose son was killed in a car accident — to complete a series of tasks that will test his ability to forgive.
