Just as the young boy disappears a young, shaven-headed, girl appears. Eleven, played by rising-star Brown, has escaped from a government laboratory and uses her powers of telekensis to help Will's friends uncover the details of his departure. Along the way they also discover a federal conspiracy and supernatural forces are working against them.

Eventually though, the youngsters manage to deliver Will back to his mother and here is where the season ends.

But the story is far from over as now Netflix have released a trailer for the much-awaited second series of the sci-fi horror, and revealed a few extra clues about what fans can expect.

As well as confirming that the action will take place during the autumn of 1984, they have also revealed that the story "will continue" - suggesting the action will take place in the same sleepy town, with the same characters we've come to know and love.

Episode names will include: MadMax, The Boy Who Came Back To Life and The Lost Brother.
