When 16-year-old Oakland California teenager, Calvin Pierce, makes a bad decision and winds up getting arrested, his mother is quick to take action. Determined not to lose a second son to the drug and gang violence of the inner city, she sends Calvin to spend the summer working for his great uncle in the heart of the Sacramento-San Joaquin Delta.
There in the predominately-white region of agriculture and recreational boating, Calvin’s a fish out of water with a chip on his shoulder. But when severed body parts are discovered floating in a slough, Calvin's summer of proving himself takes on new meaning.
Something deadly is lurking in the deep murky waterways of the Delta. Now the daunting task of containing the living incarnation of a mythical creature falls to Calvin and his ragtag posse of oddball characters.
