"he film takes place 400 years into a post-apocalyptic future, after
a virus has wiped out ninety-nine percent of the Earth's 2011
population. The survivors inhabit Bregna, a walled city-state, which
is ruled by a congress of scientists. Ćon Flux is an assassin-member
of the 'Monicans', an underground rebel organization led by The
Handler. When Ćon is sent on a mission to kill the government's
leader, Trevor Goodchild (Marton Csokas), she uncovers that she is
the unwitting part of a secret coup. This discovery brings into
question the origin and destiny of everyone in Bregna; and in
particular, Ćon's personal connection to the man she has been sent
to assassinate.

The film incorporates numerous elements from episodes of the TV
series, most notably the episode "A Last Time For Everything," as
well as from Ćon Flux: the Herodotus File, a graphic novel that was
based upon the series."
