"Too Old for This Shift" is the 1005th episode of Casualty and the premiere of the 31st series. It was preceded by "Sticks and Stones" and followed by "Fall on Me". The episode was directed by Steve Hughes and written by Matthew Barry and Andy Bayliss.
The long-running medical drama returns with a special, feature-length edition marking the show's 30th anniversary. Beginning right where the previous series left off, Connie and Grace's lives hang in the balance after they were driven off the road and into a ravine by Steph, whose own daughter was taken away by social services following Connie's meddling. Back at the ED, the team plans a surprise party to celebrate Charlie's 30 years at Holby. When news of Connie's accident arrives, the festivities are immediately put on hold, and even old faces who have arrived to mark Charlie's big day offer to lend their expertise.
