The last day on earth is coming. Bring your own booze. Kate and Albert, sister and brother, are not yet the last two human beings on earth, but Albert has high hopes.
The secluded communal farm they grew up on is - after twenty years - disintegrating, along with their parents' marriage.
They both try to escape: Kate, at seventeen, to suburbia and Albert, at eleven, into preparations for the end of the world. However, Don, the group's leader and their father, is convinced he can save everything, if only he can bring his followers into the modern age.
How? By force of personality, strict self-sufficiency and a rave with a 10k soundsystem.
Understandably, Albert and Kate have other ideas . . .
