Night Patrol is a mystery for the viewing audience to figure out. While on night patrol White Rook encounters Lieutenant Joe Kranz (played by Skip Homeier) who tells Saunders he was separated from his squad. Kranz is overly aggressive toward the Germans but agrees to follow Sergeant Saunders' orders to go along with White Rook. He wants to ambush Germans at every chance and Saunders reminds him orders are to bring back prisoners without engaging the enemy.
After being cut off from the cemetery rendezvous point, Saunders decides to take the squad to Joe Kranz's hideout. And the mystery begins to unfold. Kranz's state of mind and motivation are very believable, and it's obvious his claims about his commanding officer are true.
But the story stalls at this point. I'm critical in that there's not enough combat to carry the episode. Character development is minimal with minor interaction between Littlejohn and Nelson, and between Caje and Kirby. We also learn Kirby may be overly fond of the drink, and Caje sets him straight.
Combat interaction at the end severely belittles German intelligence; with their numbers and weaponry White Rook should not have made it look so routine. Skip Homeier is not a strong enough actor to carry the episode on his own and the script severely limits Saunders' participation thereby making this episode lackluster and somewhat boring.
Director Kennedy and Screen Writers Sparr & Jessy failed to consider what a corpse will smell like in fairly short time which makes the plot a little bit unrealistic.
