Can anyone identify a film with the following plot:

A guy goes to a Goa type party somewhere in the tropics and takes drugs.
He then goes on a trip, trying to find his father. He meets many characters on his journey, who are all in reality dancers at the party.
It is set in the tropics (probably Goa!) and the soundtrack included many goa trance classics from the mid to late nineties.

I'd love to see it again, but don't know any details about it!
