In 1941, a British infantry patrol in the Greek hills had commandeered a British tank but was under heavy shell fire from a nearby German position. They escaped into nearby cave where they came across a UFO. From the UFO they recovered a strange radio-like box. While under attack from a German aircraft, they accidentally activated the box and it sent them back in time to the Ancient Greek era. They joined forces with a force from Lemnos who were trying to defend their island from attacking Trojans. They were captured by the Trojans, but managed to get back to their tank and escape. They helped the Greeks defeat the Trojans and recapture the fort. At the end of the story, they left the island and sailed for Egypt.
