By day, Mr Yang is one of those deadpan,
dry but hilariously blunt, strict teachers we
all had when we were young.
At night, whilst trying to balance marking
with his social life and sleep he is rudely
awakened by aliens kidnapping a homeless
person in his local Peckham neighbourhood.
After bothering to get out of bed to investigate, what he discovers threatens the survival of the human species and mother nature itself.
