The Synopsis for the series three story has been released and it can be read below:

Part 1:

Rani investigates strange rumours about a demon living in a funfair at the seaside. What she finds there, however, is far more alarming than that and she makes a decision that affects not only her future, but also the futures of all those she cares about…

Far in the future, in 2059, an old Rani remembers the day when her whole life went wrong. As her younger self investigates mysterious disappearances at an abandoned funfair, she sets into motion a chain of events which unleash the terrible powers of the alien Eve.

Part 2

Alien Eve’s powers grow out of control, with everyone caught in her sinister and endless games. As the echoes of an ancient war threaten the modern world, the danger extends all the way to the year 2059. If Rani fails to change her own destiny, then everyone is doomed.

Sounds good doesn't it?
