Stuffed but dissatisfied

Sandi Toksvig’s new play opens in a Gravesend care home where five grannies and a temporary nurse are threatened by rising floodwaters. In Act One the ladies prepare for a rescue party that fails to materialise. In Act Two they build a life raft out of plastic bottles. There’s a bizarre sequence involving a silly young burglar who gets beaten up and flung through a window by a woman of 71.
