Radioactive Dreams is a 1984 post-apocalyptic science fiction-comedy film written and directed by Albert Pyun and starring George Kennedy, Michael Dudikoff, Don Murray, and Lisa Blount. The names of the two main characters are homages to noir detective fiction icons Philip Marlowe, Raymond Chandler and Mike Hammer. The film has achieved cult status and has been screened in several cult revival programs around the world.

The film begins with two boys growing up in a fallout shelter, in an attempt to escape a nuclear war. They rejoin the world in 2001, and soon acquire the activation keys of the world's last nuclear missile. They get involved in gang warfare in their new environment.

A nuclear war breaks out, expending the world's entire nuclear arsenal, except for one missile. Two children, Philip Chandler (John Stockwell) and Marlowe Hammer (Michael Dudikoff), are left in a fallout shelter cut into the side of a wooded mountain. The pair grow up in the shelter, with 1950s detective fiction and swing music as the guiding force in their learning. On April 1, 2001 (as noted by the film's title card), Marlowe succeeds in digging out the cave entrance. The pair give each other haircuts, dress in suits, and go to rejoin the world.

Philip narrates their adventure on their first day out:

My name's Philip, and this is going to be a yarn about me and my pal, Marlowe. About the day we got out of this shelter and went off into the post-nuclear world. Now, as excited as we were about leaving the shelter, it was still a joint that held fond memories. I mean, it was the only world we'd ever known. Where I practiced my magic, Marlowe, his dancing; where we both dreamed of becoming private eyes, just like the ones we'd read about.

Marlowe hopes to find their fathers, but Philip is disgruntled that they never returned, and presumes that they are dead. The mountain is now devoid of trees. The first people they find are a trio of radiation-burned mutants chasing a beautiful woman, Miles Archer (Lisa Blount). They rescue Miles, who kisses Marlowe as a distraction and steals his gun. This backfires, as she drops the activation keys to the last nuclear missile. Miles leaves, and the pair are immediately attacked by a biker gang of bald women in red wigs. Afterwards the boys discover the activation keys, which bears their fathers' names. This excites Marlowe, but disturbs Philip.

They rescue another young woman, Rusty Mars (Michele Little), from a group of armed children Philip nicknames "disco mutants." She takes a liking to Philip, and leads the two of them to Edge City which is plagued by gang warfare. Rusty takes them to a dance club, where they are captured by cannibals. They want the nuclear keys, and to eat the young men, a rarity of uncontaminated meat. Although Rusty helps them escape and apologises, Philip doesn't trust her. Just after they part ways the pair meets up with a friend of Miles who also wants the keys. After he is dispatched Miles shows up and takes them to her hideout. There she tells them about the purpose of the keys. Miles then threatens to kill them, but they escape.

Rusty has followed them to the hideout, but is attacked by the child gangsters. The pair chase them away, but Philip still doesn't trust her. He wants to shoot her, but is out of bullets. After Rusty apologises again for lying to him and originally handing him over to the cannibals he says, "That was a million years ago, and I got a short memory. In fact, I don't even remember who you are."
