Peter Olsen states Gabriel Couteau murdered a stranger who rode onto his family's farm and his teenage son, Karl, claims to have been an eyewitness to the shooting. The Olsen's charges are enough to convince Jack to make an arrest, but Clive thinks the newcomers' story is too pat. When Karl's friend, Willie Haddon, discovers that Karl couldn't possibly have seen the shooting, Peter's accusation begins to unravel.
