Black Eyed Sue.

Schuyler and Osbourne Crawl must resolve a curse that was put on their father for his part in the slaughter of a Native-American village. The curse, invoked by a woman their father would only refer to as Black Eyed Sue, can only be broken if one of the two sons sacrifices himself. Taking their father's word to heart, they naively set out to undertake this grisly task.
