The Mummy Returns is the game of the film, and as if to prove it you get the movie trailer as part of the deal. Not surprisingly, then, the general plot of the film is followed-- without giving too much away it's based around the fact that the tomb of Imhotep, a priest from ancient Egypt, has been uncovered by treasure hunters. Imhotep wants to be immortal, and in his case achieving his dream involves quite a bit of travel-- including a trip to the British Museum in London.
