"After Sarah Jane is acting suspiciously,Luke, Clyde, Rani and K-9 investigate and find that Sarah Jane has a boyfriend - Peter Dalton. they are going to get married. Clyde suspects Peter may be an alien. At the wedding the Tricksters returns and holds the church in a prison. Can the Doctor save Sarah Jane and the entire planet Earth?"
That sounds like a pretty great episode to me. I didn't know the trickster was going to be in this episode. It should be pretty amazing. The trickster is the only good enemy I've seen so far. I'd say the doctor will put a stop to him once and for all though =(
