Christmas nears, and art dealer Bernard (Alan Cumming) is having the worst day of his life: his lover leaves him, and his conniving boss, Charles (Rowan Atkinson), fires him for having high principles. Bernard's luck takes an upswing, though, when he finds an old lamp and out pops Josephus (Lenny Henry), a hip genie. After the initial culture shock, Bernard and Josephus quickly bond. But when Bernard wishes for the "Mona Lisa," these unlikely pals find themselves pursued by the police.
