Some British citizens meet at the Venetian Lido where they go to play. Between them is naughty Mr. Corner, who under the false name of Mr. Pickles goes after Mimi so her friend's son can be free to marry his own daughter. Only, he does not know that the man is in fact already married to Mimi. Little does he suspect that back home they will all meet at his very home, Braystead castle, where fireworks are to be expected.
