 Lieutenant Gerard has Richard Kimble in custody, but he has long possessed doubt about Kimble s guilt and as their train ride to Stafford proceeds, that doubt eats at him more and more, to where he agrees to give Kimble twenty-four more hours to find Fred Johnson, known to be heading to Stafford to find the man who bailed him out of jail in Los Angeles. When they meet Richard s brother-in-law Leonard Taft, they learn that a man phoned his wife Donna claiming Taft was in the house the night of Helen Kimble s murder. It turns out there was indeed someone else in the house that fateful night, and Fred Johnson confronts the man who was also there, demanding a hefty blackmail payment. By good fortune Gerard learns the truth and he and Kimble must confront Fred Johnson at a shuttered amusement park, where a gun battle leaves Gerard injured and leaves Kimble one final chance to defeat Johnson and put an end to years of grief and flight once and for all.
