For a year now, the Roman legions under the command of Aulus Plautus have been fighting in Britain. The order of Emperor Claudius is unequivocal: capture the leader of the Britons Karatak. The Romans prepared a cunning trap for him. However, Karatak was even more cunning .. Now a huge horde of natives is opposed only by the Third cohort, in the ranks of which the centurion Cato fights - a young but promising commander. The Romans survived in a bloodbath, but Karatak managed to escape.. The order of the emperor is not fulfilled... The third cohort is subjected to decimation every tenth warrior must be executed. By accident, the convicts manage to escape . Now Cato and his brothers-in-arms have become outcasts, enemies for everyone both for themselves and for strangers. But the Roman legionary will never back down to anyone and nothing.
