text: Three friends are driving cattle in Australia in 1939: the restless Bluey Donkin, easy-going Milo Trent and English Peter Linton, who is in the country on a working holiday. Squatter's daughter Kate Carmody is in love with Bluey but he refuses to be tied down to any one woman. War breaks out and the three men enlist in the Australian army and are assigned to the 9th Division. They ship out to Africa. After early successes against the Italian army, the army is besieged in Tobruk. In between attacks, the men have comic encounters with a barber and Peter falls for a nurse, Sister Mary, after being wounded. There are several subsequent attacks in which all three soldiers are wounded. Peter Linton is killed but the others manage to repel the Germans. Bluey and Milo are then transferred to New Guinea, where Bluey is injured and Milo killed by a sniper. Bluey manages to kill the sniper and returns to Australia, where he is reunited with Kate.
