The Red Herring bar in Boston was robbed by a gang of gun-toting Santa Clauses on Christmas Eve. During the heist the bumbling crew of culprits unearth a century-old skeleton leading them to believe the booty is cursed.
Bartender Mullet McGuffin realizes he cannot rely on the Boston constabulary to solve the crime, so he enlists the aging Bass sisters, aka the "Psychic Siblings," to exact justice and get back the stolen goods. Christmas at the Red Herring is a merry, metaphysical mystery.
