Bernard's monastery are in a jam. Abbot Costello and his four beleaguered brethren have just learned that a real-estate developer is about to turn their monastery into a gambling hall called Bernie's Casino Royale. Unless the merry Men in Brown can raise $250,000 dollars by midnight, they are done for. Luckily, the Brothers have a divine plan. They've rented religious radio station WGOD for the night and are hosting a radiothon fundraiser with plenty of singing, dancing, and vaudeville routines. Abbot Costello, Brother Lee Love, Brother Brooks, Brother Clarence and Brother Forte all take turns strutting their stuff, and the pledged donations from the listeners start streaming in. But unbeknownst to the other four, one of the monks is really a devil in disguise and is out to sabotage their plan. Good and evil race to beat a midnight deadline in this hilarious hit musical.
