This episode is not an exceptional one among the series. Two cops investigate around several murders. Nothing special. And beside this, you have the usual but so well made the private lives of those same cops, their private affairs, especially Bill Shatner. He is very poignant and convincing here and you have a very touching element in this tale. I can't explain exactly what, I prefer let you see by yourself. I can't tell you anything more unless to spoil the story. Good screenplay and good acting.
The ending doesn't look like a POLICE STORY one, if you compare with the others.
