Lost Treasure of the Grand Canyon

When a group of archaeologists goes missing after traveling deep into the Grand Canyon in search of a lost civilization, it's up to the team leader's daughter (Shannen Doherty) to organize an rescue expedition. What she discovers instead is an ancient Aztec city. To save her father and his colleagues, she'll have to go head-to-head with a deadly flying serpent that guards the city in this Sci Fi Channel feature set in the early 1900s.
