1930s England, it’s Christmas Eve in the manor house of the bumbling aristocrat, Sir Walton Gates and his wife Grace. His daughter Emma from a previous marriage arrives from town with her new companion in tow, the dashing James Washington and added to the mix is Sir Walton’s estranged brother Archie, recently returned from years spent in Australia, bringing with him an appetite for mischief and a dodgy accent.
Enter England’s most confused police officer, Sergeant Pratt, who unwittingly kicks a hornet’s nest of English gentility and the evening soon descends into chaos with hilarious consequences.
