In this episode, 'Deliver Us Some Evil,' Ritter's character is asked by Van Heusen to pull one last big job. To rob a very wealthy elderly lady of her valuables, including coins which Van Heusen wants. Van Heusen is the ring leader of men fencing stolen goods. And to add, at the end; Savalas and Sadoff are posing for a photo after his character and others are caught in a warehouse with the 8 barrels of goods stolen. This is, as far as I know, where there is a link between The Poseidon Adventure and Beyond The Poseidon Adventure.
