In 73 AD, in Masada, Judaea, a band of Jewish zealots were losing in a war against the Romans. Eleazar ben Jair, the leader of the group, devised a plan: they would all kill each other.

When the TARDIS appeared there, Ian Chesterton and Barbara Wright joined the Jews, while the First Doctor and Susan Foreman joined the opposing Roman camp.
