And we're back to history once again, as the TARDIS arrives in 12th century Palestine. Barbara is once again kidnapped, this time by Saracens, and the king grants Ian the right to ride off and find her - knighting him "Sir Ian of Jaffa" for the purpose. Meanwhile the Doctor and Vicki stay behind and try unsuccesfully not to get caught up in courtly intrigues, eventually making an enemy of the Earl of Leicester and having to flee the court. Meanwhile, Ian rescues Barbara and they all meet up back at the TARDIS and narrowly escape the Earl of Leicester's men, hot on the Doctor's heels.
