The first episode of the second season continues the plot of the last episode of the previous season, starting with the first official meeting between Sherlock (Benedict Cumberbatch) and Watson (Martin Freeman) and Moriarty (Andrew Scott) who were threatened by bombs and sniper rifles. Then Sherlock met the mysterious woman Irene Adler (Lara Pulver), a rival of equal strength and a woman who made his heart beat, in a case where he accepted an important commission from Buckingham Palace. This time Moriarty made the public believe that all of Sherlock's deeds were fictitious, making him a pseudo-hero with a discredited reputation. In order to completely defeat Sherlock and force him to jump off the building, Moriarty immediately shot himself. What is the ending? Will Sherlock fall into his trap? All the excitement is in the second season.
