The Gaelic Curse follows Bailey O Farrell (played by someone's character) and Limp O Reilly as they try to break a curse that has plagued their family for generations. The curse, originally placed on two servants who killed a Gaelic king, causes each generation to receive a new affliction - in this case, Bailey suffers from a hump on his back and Limp has a limp. As they navigate their way through comedic misadventures, the pair also find love with local women and must outsmart the Devil himself, who plays tricks on them until he's redeemed by love. Along the way, the Devil's sister offers crucial help in breaking the curse.
