Murder Party 2007 NTSC [RQT]

In New York, during the Halloween, the lonely traffic warden Christopher "Chris" S. Hawley finds the invitation to a murder party on the street, and during the night, he wears a costume of a knight of the round table and goes. He makes a bread of pumpkin and raisin, leaves his cat Lancelot at home and takes the subway to the party. He finds that the address is in an abandoned warehouse and inside there are six people only. One of them tells that it is too early yet and soon he is subdued and chained to a chair. He learns that they are a group of drugged deranged artists that intend to kill him as part of their art, in the beginning of a gory night.
