Climate change brought on by an ‘event’ leads to a sort of Mad Max future, with nomadic communities of desert-adapted vehicles/ships forming, the better to protect themselves and to seek water.
A tight drama is enacted, with a bit of backstory, and an ending offering the potential of a sequel. FWIW I’d vote for one.
note to self : check to see if Americans do indeed spell drought ‘draught’ as in GvG’s introduction
