This leads to a panic among the drug suppliers and as a result Rave Parties are cancelled and the drug supply comes to a halt. The drug dealers gather for a meeting lead by Zoey (Bipasha Basu). Zoey guarantees them that their drugs will be in safe hands, if they give them away to a person named Michael Barbosa, a person who has no identity and moves like a shadow and has helped them out for ages.
