They radio for additional support and a veteran police team arrive at the crime scene. One of the veteran policeman is killed in the midst of the robbery, and his partner places fault on Danko. The veteran policeman makes the suggestion that Danko be appointed to ride with him, a suggestion that turns out to have almost catastrophic results. (thetvdb.com)
