This is an enjoyable serial. The Doctor, Ian, Barbara, and Vicki arrive outside the town of Jaffa during the Crusades. Saracens kidnap Barbara, and the others befriend Richard the Lionheart, the king of England.
Ian wants to go get Barbara immediately. (Of course he does! Again, I'm on record as thinking that Ian and Barbara have a thing for each other.) The TARDIS crew ask Richard for help, and one of his knights helps convince him to send Ian to the sultan's camp. King Richard knights Ian, and off he goes. Meanwhile, El Akir, the obvious baddie among the Saracens, is doing some serious plotting. He doesn't like Barbara at all. The Doctor and Vicki hang out with the king and his sister, Princess Joanna. Joanna finds out that Vicki is really a woman and stops her from continuing to pretend to be a boy.
The Doctor and Vicki always have a good time together. He's much nicer to Vicki than he was to Susan. I'm not sure if that's his character evolving or if it's a deliberate choice. Vicki is sweet and smart and not afraid of her own shadow, but the Doctor also continues to be nicer to everyone in general.
Back to the story...More plotting. The king wants to marry his sister to the sultan's brother and forge a peace. She's having none of that. There is intrigue upon intrigue.
Eventually, Ian finds Barbara and everyone makes their way back to the TARDIS. There's a funny bit at the end. The knights see the TARDIS leave, and they think that "Sir Ian" has been whisked off by fiends- poor Sir Ian! Heh.
When I looked at the episode list, I realized that I'm almost to the end of the Barbara and Ian era. I hate to see them go!
