Spectre (2015 film) [SEP] Plot
A posthumous message from the previous M leads MI6 agent James Bond to carry out an unauthorized mission in Mexico City on the Day of the Dead, where he stops a terrorist bombing plot. Bond kills Marco Sciarra, the terrorist leader, and takes his ring, which is emblazoned with a stylised octopus. Upon his return to London, Bond is suspended from field duty by Gareth Mallory, the current M, who is engaged in a power struggle with Max Denbigh (whom Bond dubs "C"), the Director-General of the new, privately backed Joint Intelligence Service formed by the merger of MI5 and MI6.
