A the guy who was trapped there since 1996.

A brief
outline of the film is that four high school kids are stuck inside a game, they
need to work together to be able to get through various dangerous obstacles such
as (hippos and Rhinos and Bobby Cannavale) the object is to restore a precious
gem to the place where it belongs on top of mountain, if they don’t achieve
this then they will be stuck in the game forever. The proof is Nick Jonas who
is the avatar of the guy who was trapped there since 1996.
