Young Sherlock Season 1

Season 3

Season 3 propels the clone sisterhood into uncharted territory as they confront the unsettling truth that they are not alone. Just when they believe they know their enemies and allies, this chapter reveals that the clones are more vulnerable than ever. Highly trained, identical male soldiers raise more questions than answers. Who are these new clones? Who created them? And more importantly, why do they exist? Sarah, Cosima, Alison, and Helena are stronger together than apart, but this season tests that bond to its core. Will they forge towards their truth, or fall at the feet of those who seek to control them?
