Dreadful
There's so much wrong here, I don't even know where to begin.
Reed has been studying Egyptology and sees some hieroglyphics in a museum that he takes to mean a pharaoh who was blind had a radioactive herb that made him see again. Thinking this can possibly cure Alicia, the FF travel to Doctor Doom's abandoned castle to use his still working time machine to travel to ancient Egypt. There they encounter Rama-Tut, a descendant of Doom's who traveled to the past in a time traveling sphinx to become Pharaoh. He enslaves them with a ray gun, but doesn't count on the hot desert sun which causes the Thing to turn back to Ben Grimm breaking the mind control. Ben gets the gun and fires it at Sue, but turns back to Ben Grimm and thus a slave again (huh?). Rama-Tut (who was blinded, but a rare herb reacted with the radiation of his ship to give him sight again) gets the drop on Sue because she can't figure out how to fire his ray gun which the Thing just picked up and fired. In the end Rama-Tut escapes leaving the sphinx behind, and the FF return to the future with the optic nerve restorer, but it's not with them when they arrive and Reed - always in the know - alerts us that "This earliest device had one critical fault... it will transport nothing with radioactive properties from the past to the future or vice versa!", how he knows that, and why he didn't know it before they even bothered with all of this... who knows.
Frankly this stuff is just not worth the time it took to produce, or even the time it takes to read.
