Wavelength is a 1983 science fiction film written and directed by Mike Gray and starring Robert Carradine, Cherie Currie, and Keenan Wynn.
Two young Americans learn that a small group of child-like space aliens are marooned on Earth and are being held prisoner at a top secret military facility. The couple then decide to liberate the extraterrestrial castaways and help them make a rendezvous with a rescue ship sent from the alien home planet.
Bobby Sinclaire (Robert Carradine) , a failing Californian musician, meets telepathic Iris Longacre (Cherie Currie) in a bar and they begin a relationship. At Sinclaire’s apartment, Longacre begins to hear things others cannot. The young couple discover the voices are from a childlike race of aliens being held by the U.S. government after their UFO crashed. The government plans to use the trio of aliens for experimentation and dissection in an supposedly abandoned underground bunker located near Sinclaire’s apartment. The couple decides to liberate the aliens and help them return them to their mothership.
This movie was never released on DVD and includes a Fabulous Soundtrack by: Tangerine Dream.
