Nightbreaker (also known as Advance to Ground Zero) is a 1989 American historical drama television film directed by Peter Markle and written by T. S. Cook, inspired by the book Atomic Soldiers: American Victims of Nuclear Experiments by Howard L. Rosenberg.[1] The film stars Martin Sheen and Emilio Estevez as older and younger versions of fictional neurologist Alexander Brown. It also stars Lea Thompson, Melinda Dillon, and Joe Pantoliano.
Dr. Alexander Brown (played by Sheen in framing scenes and Estevez in flashbacks) reflects on his involvement in the exposure of American soldiers to radiation in the proving grounds in Nevada in the 1950s after he is approached by a man who is dying of cancer due to the tests.
