Irish Luck was one of a handful of Monogram actioners starring Frankie Darro as a crimesolving bellboy. The son of plainclothes detective, Buzzy O'Brien (Darro) is naturally suspicious of some sinister activities transpiring at the hotel where he works. When a murder occurs, Buzzy offers his assistance to flustered flatfoot Lanahan (Dick Purcell)-and, surprise of surprises, he solves the case. Mantan Moreland is a riot as a timorous bellhop who keeps stumbling upon dead bodies. Irish Luck was reworked in 1944 as The Adventures of Kitty O'Day.
