Just why do humpback whales sing?That's the question that has marine biologist Nate Quinnand his crew poking, charting, recording andphotographing very big, wet, gray marine mammals. Thatis, until the extraordinary day when a whale lifts itstail into the air to display a cryptic message spelledout in foot-high letters: BITE ME.Trouble is, Nate's beginning to wonder if he hasn't spentjust a little too much time in the sun. 'Cause no oneelse saw a thing- not his longtime partner, ClayDemodocus; not their saucy young research assistant; noteven the spliff-puffing white-boy Rastaman Kona (nePreston Applebaum). But later, when a roll of filmreturns from the lab missing the crucial tail shot- andhis research facility is trashed- Nate realizes somethingvery fishy indeed is going on.
