Bejabbers! Sure an' some heathen has gone and stolen the Blarney Stone. Yes, Top O' the Morning is set in Ireland, or at least Hollywood's idea of Ireland. American detective Bing Crosby arrives on the Auld Sod to investigate the theft of the Stone, while the local constabulary, represented by Barry Fitzgerald (his third teaming with Crosby) and Hume Cronyn, assist Bing in his inquiries. Cronyn turns out to be the heavy of the piece, but Crosby is too busy romancing leading colleen Ann Blyth to concern himself. The "faith 'n' begorrah" business is spread a bit too thick in Top O' the Morning, but not as thick as Barry Fitzgerald's near-impenetrable brogue.
