A package holiday abroad turns into an hilarious adventure in the hands of the Carry On crew. On the island of Elsbels, their stay at the Palace Hotel is disrupted by bad plumbing, a restaurant filled with mosquitoes and a dawn chorus of cement mixers. This is on top of the inter- and extra-marital complications and misunderstandings. Will all be well, or will all be hell? Innuendos and gags abound in this classic British romp.
