The film hasn't aged well, yet there's still something worthwhile about the narrative. The premise involves the US Navy during World War II attempting to develop technology that would render Allied ships undetectable by their German adversaries. A device is created and tested aboard the USS “Eldridge,” but the experiment is cut short when two crew members vanish, abruptly finding themselves forty years in the future. "Longstreet" (Eric Christmas), the scientist responsible for the invention, tries to recover them. Simultaneously, displaced individuals “David” (Michael Paré) and “Jimmy” (Bobby Di Cicco) face difficulties in 1984; Jimmy experiences a troubling event at a hospital, prompting them to seek out the scientist and hope his future self will believe their account and assist in returning them to their proper time. The writing demonstrates some consideration for the plot's development, although I found the performances somewhat lacking. Despite this, it employs its visual effects creatively, offering a unique perspective on how time travel might function and affect two young men who were largely sheltered from the world. A romantic subplot emerges for “David” involving “Allison” (Nancy Allen), who is easily convinced, and there's also an attempt to ground the science with some degree of plausibility, avoiding a simplistic approach like that of the "TARDIS." It has the feel of a made-for-television production, but it’s still worth viewing.
