AS MARTIN CLINGS TO LIFE FOLLOWING A SHOOT OUT, JACK, SAMANTHA AND DANNY SEARCH FOR THE MERCENARY RESPONSIBLE FOR OPENING FIRE ON MARTIN, DANNY AND THE TERRORIST IN THEIR CUSTODY, ON A REBROADCAST OF THE FOURTH SEASON PREMIERE OF "WITHOUT A TRACE," THURSDAY, JULY 13

"Showdown" -- Jack, Samantha and Danny search for the mercenary who escaped after killing the terrorist in Martin and Danny's custody and leaving the bullet-riddled Martin at death's door, on a rebroadcast of the fourth season premiere of WITHOUT A TRACE, Thursday, July 13 (10:00-11:00 PM, ET/PT) on the CBS Television Network. John Showalter directed the episode written by David Amann, one of the series' co-executive producers. (Originally broadcast 9/29/05)

Martin and Danny attempt to dodge a hail of bullets as a mercenary and his cronies attempt to kill their true target, an F.B.I. detainee whom Martin and Danny were transporting. Despite some quick thinking from Martin, who uses the car as a weapon against the shooters, and Danny, who manages to shoot one of the perpetrators, their prisoner is killed and Martin is left gravely injured. Now, Jack, Samantha and Danny try not to let their concern for Martin hinder their efforts to hunt down the mercenary -- which becomes more complicated once Martin's father, F.B.I. Deputy Director Victor Fitzgerald, and the Department of Homeland Security take active roles in the case. Meanwhile, Vivian's heart-surgery appears to have been a success.
