Barry has a secret - he wants to get Glenda a water-bed for Christmas.

Compo, Clegg and Foggy encounter a stranger from the Heckmondwike Extraterrestrial Club who foresees aliens landing in Yorkshire.

Clegg is dismayed when Howard leaves with him a "picnic accessory" which he plans to collect later - Marina! He will only collect her when Pearl is safely away, but that could be some time, as the ladies are coming to tea next door. Auntie Wainwright's advertising dummy becomes key in the plan as Truly and Billy help Clegg get free of the imposed house guest.
