That's the one. All I remember is everyone fighting with everyone else all the time. Especially Catherine talking Bailey into lying to Richard and sending somebody to take over his job and then everyone fighting about that.
They spend half the season trying to tell us that Alex is going to jail which of course he's not, and then that episode where three of the characters operate on someone in jail for no apparent reason, and then everybody just fights. And the only redeeming grace is when Maggie's mother shows up.
