NARRATOR: Dahshur,
15 miles south
of Cairo, it's one
of Egypt's most
mysterious royal graveyards.
Today, only a handful
of pyramids survive.
But the remains of
many more lie hidden
beneath the desert sands.
Egyptologist Dr. Chris
Naunton has spent his career
hunting for these lost tombs.
He has come to Dahshur, where
Egyptian archaeologists have
made a thrilling discovery.
 This is a pretty
exciting moment.
We're in-- it's a amazing
kind of lunar landscape.
And this is the Bent Pyramid
just slightly closer to us,
and what's known as the
Red Pyramid behind it.
But we're going to a much less
well-known part of the site,
where something very
intriguing, to say the least,
has been uncovered
just very recently.
NARRATOR: This crater was
the site of a large quarry
until workers stumbled upon
blocks of finally cut limestone
buried deep in the sand.
Egypt's Ministry of
Antiquities began to excavate.
Excavations have
revealed a passage
that once led from the entrance
to deep under the pyramid.
The stairs lead to an
underground complex,
the heart of the pyramid.
These huge blocks are
protecting the only access
to the chamber and
any mummy and treasure
that may be hidden inside.
And unlike any other
pyramid found so far,
it still appears to be sealed.
Egypt's Ministry
of Antiquity has
granted permission
to raise the capstone
to reveal what lies within.

Finally, after three
days of effort,
the tomb gives up its
secrets for the first time
in almost 4,000 years.
But what's inside is a shock.
CHRIS NAUNTON: Oh, goodness me.
NARRATOR: Its contents
are in disarray.
The archaeologists hoped
to be unveiling treasure.
But now, there's a
mystery to solve.
 There are two
questions here that we
need to start trying to answer.
One is, who was buried here.
Who was this pyramid built for?
And then secondly, how is it
that an apparently completely
sealed, unbreached
burial chamber
comes to have been disturbed?
NARRATOR: It's becoming
clear they've stumbled
upon an ancient crime scene.
Someone got here first and
robbed the burial chamber.
