It needs a main hook,then it needs a smaller hook for each episode

I'd consider the main hook to be the fact the the insect pilot who unwittingly
destroyed Roman Britain civiliation is the disgraced fellow who has to land
a alien starship with broken landing engines in Lake Erie in 1937.
Smaller hooks might be from the interactions of the disgraced pilot with a land
of the Great Depression,with bankers foreclosing farms and with
WW2 just around the corner.If the starship had come down during a raging
storm and the War of the Worlds broadcast,its quite possible the
fellows arrival was passed by
