Escape Through Time

Throughout all time, there's never been an adventure quite like this...

Some time in the 21st century, Kovarick, said to be the most evil man who ever lived, is met by a resistance force. One of their members, Dr. Bahler, invents a time distorter held within a ring, which he uses to go back to ancient Egypt, where he dies. 75 years before he left, the ring is found by scientists, who are killed by a small mafia group, but not before it is thrown to a bum, who pawns it for fifty cents.
