In a beautiful alpine resort our two heroes, the debonair army Captain Clive Morton (Nigel Patrick) and the clumsy upper class Humpy Miller (David Tomlinson), are guests in a family run hotel. Here they catch their first glimpse of the most stunning scenery in all of Switzerland... the gorgeous Mary (Jill Day), the hotel owner's daughter. Our two heroes do battle for Mary's affections only to find that a wealthy Greek, Gaston Nikopopoulos (Leo McKern), also has his eye on the prize. Clive shows off his skiing prowess while Humpy wraps himself around a tree as fun and frolics ensue on the slippery slopes. However disaster strikes our valiant English suitors when they succumb to a bout of chicken pox and are confined to their rooms. Slowly nursed back to health by Humpy's overbearing childhood nanny (Kathleen Harrison), will they be able to snare their prey or will the lovely Mary fall for the Mediterranean charms of the ghastly Gaston??
