Dawn French returns to sitcoms in Can You Keep A Secret? The Vicar of Dibley star plays widow Debbie Fendon - granny, lawn bowler, tinpot dictator - who will stop at nothing to make sure her family is protected. Unfortunately, most of the time the person they really need protecting from is her. When her hermit-like husband William (Mark Heap) unexpectedly dies, she makes an outlandish decision that will put the family under more pressure than ever before.
