In Harm's Way (2)

In last year's season finale, a vicious serial killer who set his sights on wealthy members of Dallas society was successfully apprehended, with Walker, Trivette, Alex and C.D. all risking their lives trying to stop him. But when Walker and Alex transported crucial evidence for a potential conviction, their plane mysteriously crash landed and trapped them inside. In the new season premiere, the serial killer awaits his trial, perilously close to being released from custody and ready to flee the country, as Walker and Alex struggle against all odds to get to the courtroom with the critical evidence that will convict him.
