Be one of the first 50 people to bring your student ID to Cinemapolis for The Cove screening this Friday, and you can be one of the chosen few to receive a free ticket to the documentary that the New York Times called  "one of the most audacious and perilous operations in the history of the conservation movement."

The Cove, easily one of the most revolutionary documentary films made recently, follows Ric O'Barry on an expose of the heinous activities going on in an otherwise scenic cove in Taiji, Japan. Protected by barbed wire fences and armed guards, a six month-long slaughter of thousands of dolphins takes place every year. Dolphins are herded into the cove by local fishermen; for them, it's the killing of competition, as the dolphins represent a rival for daily fish consumption.

O'Barry and his crew infiltrated the operation using divers and high-definition cameras camouflaged as rocks, as the local police and fisherman provided tight security at the site of the brutal slaughter. An espionage film as well as an environmental documentary, it's not a screening to miss. The Cove has already won many awards, including the Audience Award at the 2009 Sundance, and the Best Feature Film at the 2009 Nantucket Film Festival.
