The year is 2051. Location: SATAZIUS, a long-abandoned planet. The cruiser Agano was on patrol when it was attacked and stricken by a confederacy of space pirates that had established a base on SATAZIUS. The pirates attacked the Agano intending to steal the assault ship ‘Trafalgar’ that was stowed aboard the Agano, but the Trafalgar made a successful emergency escape. The crew of the Trafalgar calculated the probability of successfully escaping the pirate overrun planet at 0.02%; the probability of charging into and successfully destroying the pirate base was 1%. Taking the higher probability escape plan, the crew of the Trafalgar turned their ship toward the pirate horde and began their charge into the heart of SATAZIUS.
