S14 E3: Heritage of Anger

Ex-con John Dundee, a friend of the Cartwights, is being released from prison. Ben tries to help John readjust to society, but John wants revenge on those who sent him to prison - namely, ex-business partners, Anders, Bartlett and Sangster. Worse, the bad guys, who are friends with a corrupt lawman, are hatching a plan to send John back to prison ... this time, for murder.
