Alice & Jack (2024)

S3E2 The Undertakers

At Adelphi Park, a luxurious rest home, all the residents are wealthy millionaires. However, most of them are avoiding any visitors, including Professor Renter, who was set to travel to America with Steed to present his newest invention. Renter's wife seems either unable or unwilling to assist him, and intriguingly, their neighbor Madden, who is also a millionaire, has vanished without a trace.
