The Turkish Sultan (Rik Mayall) is making a mint from trade heading to Europe from the East, however he discovers that a Portuguese map maker called Columbus (Jim Dale) is planning to find an alternative sea route which could ruin him. The Sultan sends his spy Fatima (Sara Crowe) and agent Achmed (Alexi Sayle) to stop him. Columbus has got funding from the King of Spain (Leslie Phillips) and is going to set sail...
Well we all know what happens of course. This is the usual mix of terrible jokes, double entendres and mild saucy antics that made the Carry On series such an icon of British comedy.
Unfortunately apart from Jim Dale the old Carry On crew had either passed on or did not want to be involved with this film and much of the humour falls flat. Terrible lines which Sid James or Kenneth Williams made hilarious unfortunately fail without them. Some of the humour, such as the Inquisition scenes, does work but mostly because it has been updated a bit.
It's a terrible shame it had to end this way.
