Prior to his box-office success with The Sixth Sense, Bruce Willis was paired with another young lead in this minor thriller, which is a tad more imaginative than most action fare. Willis stars as a renegade government operative who becomes protector of an autistic child (Miko Hughes) who has cracked the supposedly impenetrable Mercury security code. Alec Baldwin plays the crooked national security man who's determined to hunt them down. Director Harold Becker manages to impart a little depth to the relationship between Willis and Hughes among all the chases and shoot-outs, but the psychological backdrop is too contrived.

Renegade FBI agent Art Jeffries protects a nine-year-old autistic boy who has cracked the government's new "unbreakable" code.
