After discovering a 64-million-year-old message written on a cave wall, Dr. Frank Reno, a
scientist on the original Philadelphia Experiment, leads a group of modern-day Navy SEALs
back to the Cretaceous to rescue those who were lost back in that 1949 experiment. The
consequences? Machine-guns-vs-dinosaurs, a T. rex in Los Angeles, and potential paradoxes for
the original travelers.
