Cliff's:

Keawe, a poor Native Hawaiian, buys a strange unbreakable bottle from a sad, elderly gentleman who credits the bottle with his fortune. He promises that an imp residing in the bottle will also grant Keawe his every desire.

Of course, there is a catch. The bottle must be sold, for cash, at a loss, i.e. for less than its owner originally paid, and cannot be thrown or given away, or else it will magically return to him. All of these rules must be explained by each seller to each purchaser. If an owner of the bottle dies without having sold it in the prescribed manner, that person's soul will burn for eternity in Hell.

The bottle was said to have been brought to Earth by the Devil and first purchased by Prester John for millions; it was owned by Napoleon and Captain James Cook and accounted for their great successes. By the beginning of the story the price has diminished to fifty dollars.

Keawe buys the bottle and instantly tests it by wishing his money to be refunded, and by trying to sell it for more than he paid and abandoning it, to test if the story is true. When these all work as described, he realizes the bottle does indeed have unholy power. He wishes for his heart's desire: a big, fancy mansion on a landed estate, and finds his wish granted, but at a price: his beloved uncle and cousins are killed in a boating accident, leaving Keawe sole heir to his uncle's fortune. Keawe is horrified, but uses the money to build his house. Having all he wants, and being happy, he explains the risks to a friend who buys the bottle from him.

Keawe lives a happy life, but there is something missing. Walking along the beach one night, he meets a beautiful woman, Kokua. They soon fall in love and become engaged. Keawe's happiness is shattered on the night of his betrothal, when he discovers that he has contracted the then-incurable disease of leprosy. He must give up his house and wife, and live in Kalaupapa—a remote community for lepers—unless he can recover the bottle and use it to cure himself.

Keawe begins this quest by attempting to track down the friend to whom he sold the bottle, but the friend has become suddenly wealthy and left Hawaii. Keawe traces the path of the bottle through many buyers and eventually finds a haole in Honolulu. The man of European ancestry has both good and bad news for Keawe: (a) he owns the bottle and is very willing to sell, but (b) he had only paid two cents for it. Therefore, if Keawe buys it, he will not be able to resell it.

Keawe decides to buy the bottle anyway, for the price of one cent, and indeed cures himself. Now, however, he is understandably despondent: how can he possibly enjoy life, knowing his doom? His wife mistakes his depression for regret at their marriage, and asks for a divorce. Keawe confesses his secret to her.

His wife suggests they sail, with the bottle, to Tahiti; on that archipelago the colonists of French Polynesia use centimes, a coin worth one fifth of an American cent. This offers a potential recourse for Keawe.

When they arrive, however, the suspicious natives will not touch the cursed bottle. Kokua determines to make a supreme sacrifice to save her husband from his fate. Since, however, she knows he would never sell the bottle to her knowingly, Kokua is forced to bribe an old sailor to buy the bottle for four centimes, with the understanding that she will secretly buy it back for three. Now Kokua is happy, but she carries the curse.

Keawe discovers what his wife has done, and resolves to sacrifice himself for her in the same manner. He arranges for a brutish boatswain to buy the bottle for two centimes, promising he will buy it back for one, thus sealing his doom. However, the drunken sailor refuses to part with it, and is unafraid of the prospect of Hell. "I reckon I'm going anyway," he says.

Keawe returns to his wife, both of them free from the curse, and the reader is encouraged to believe that they live happily ever after.
