there is a tv series called THE TRIPODS which I believe was made in France or England, and I think ex-JWs made it...
in it these children notice that when their friend reach the age of accoutability, they have this CAP surgicaly placed on their skull and
they become subservient robot like entities with little life or creativity in them.[baptism?]... and that is not for them.... so they run away.
there are these menacing machines the height of trees with three legs which try to hunt them down.
the seek a sanctuary they heard about in the mountains.
when they finally meet up with the apostates [I mean resistance] they learn of a plan to infiltrate the CITY OF GOLD [bethel] where the tripods have their main base and powerplants... they must get a false cap and pretend to be capped and participate in an olympic like competition to be deemed worthy to enter the city of gold... which is the hope and dream of every capped person... much like many naive JWs view bethel.
once they get in they discover the tripod rulers are aliens, the city is filled with dangerous gases which kills off the young olypiads very quickly by rapid aging, much as bethel seems to do by hard repetitive work and free flowing alcohol to relieve the pressure.
