Long Island is home to Mike Callahan's bar, which is, like many other establishments of its kind, a place for people to share their personal problems with the friendly all-knowing bartender and drown their sorrows in alcohol. One small difference between this particular bar and most others is the clientele: mythological beings, time travellers, and aliens all feel at home at Callahan's. So does Jake Stonebender, a traveling guitarist with a tragic past, inclined to help those in need. Chatting with the colorful patrons of the bar, Jake finds out that a few of them do need his assistance, and will proceed to help a vampire find his long-lost love, solve the moral dilemma of an alien whose pacifist thinking is not approved by the majority of his race, save the rainforest from destruction, and perform other good deeds that will perhaps prove to the Powers-That-Be that humanity can be allowed to exist.
