Time Bomb - S9.E11

As payback for Jace Sampson's cooperation in Sharpe's takeover of Falcon Crest, Richard talks Jace into making an investment after which Jace loses all his money. Pilar and Lance's estrangement worsens. After Walker catches Richard and Lauren kissing, he confronts them with dynamite strapped to his chest, which is set to go off when the timer runs out. Rather than kill Lauren and the boys along with Richard, Walker runs outside just as the dynamite explodes.
