The trait of forgiveness is explored in this one-off Everyman documentary. Graham Dudman, managing editor of The Sun, travels to Liverpool to try to apologise for the paper's coverage of the 1989 Hillsborough football disaster; the parents of a murdered teenager have contrasting attitudes to their son's killers; a mother and daughter try to heal a romantic rift; and a man in his early 40s seeks an apology for a teacher's childhood criticism.
