This episode starts off with Murdoch being chased by 2 men with guns in Montreal. He gets wounded in the arm and hides in a pub.
The female owner of the pub hides him when the men come in to look for him and he stays hidden. They tell her he is a killer. He talks to her later and does not know why the men are chasing him it has something to do with a murdered man. He has amnesia. He does not know who he is, where he is or much else accept that he was taken off the train.
He tells the pub owner Anna what he remembers and how he has to go to the apartment of the man that he was accused of killing so he can figure out what happened to him. She is very helpful and trust him. She calls him "Harry". She starts to care very much for him.
Murdoch series introduces a lot of new scientific products in the making and used to help solve crimes or commit them. This is one of them. It is a long telescope attached to a special rifle that shoots long range.
This is the first episode I ever saw where Murdoch uses a hand gun and shoots at someone. It has a good ending, very moving but also sad.
