When construction unearths something unexpected, Susan Storm is called in - not as a super hero but an archaeologist!

But when the bones she uncovers - tens of thousands of years old, dating back to the first arrival of humans in the Americas - turn out to be female...and matching her build...and wearing the shredded and decayed remains of what appears to be BLUE FABRIC constructed of unstable molecules, she must accept the fantastic: Dr. Susan Storm is going to DIE deep in Earth's prehistory...

...and that time is coming sooner than she might think!

Also in this issue: an anniversary date for Reed and Sue! So Sue gets both inarguable evidence of her own death AND some romance.

Not in that order though.
