Alex, Jess and Dave investigate when members of the local zumba class start acting like zombies.
Something strange is happening on Cherry Tree Lane. Members of the local Zumba class are mysteriously collapsing and even more mysteriously coming back to life.
Alex, Jess and Dave have to put a stop to it before Alex's mum and nan join the living Zumba dead or there'll be no family Christmas.
But why are the 'Zumbies' curiously drawn to the Christmas lights? What does the Octopus sign mean? And who is the evil genius behind it all?
NOTE : Various people are poisoned and mind controlled, and there are some scenes in which the main characters narrowly escape death. This is all done in an over the top, action move style, but may upset more sensitive readers.
