Susan Morrison's life has been dominated by what some might call a hobby, but psychiatrists call an obsession. The object? A 46,000 tonne liner who went to her watery grave in 1912. This show is a look at the things that make people bore the arse off their families and friends. It's a look at why kings give up crowns, why people shouldn't be left with nothing to do and why Trekkies are cheats in the obsession game.
