Using a little bit of friendly blackmail on his bank manager brother-in-law Richard, Ron Archer and son Trevor set out to purchase the long derelict Midbourne Pier.

After securing its purchase from the local council, Ron, Trevor and Richard go to check the conidition of the pier. Well, the bit they can reach anyway, what with the middle having been blown up during the Second World War...

Ron decides that the pier's superstructure needs checking - of course, it's got to be done at night to avoid attention.
