When Steve's five man SAS patrol inadvertently spark a time portal, they find themselves in 10th century Viking Denmark. A place far more dangerous and lawless than modern Iraq. Join the SAS patrol on this action adventure into the depths of not only a hostile land, far away from the support of the Allied front line, but into another world...another time.

This is the day Australia fell.
