Written and directed by Steve DeJarnatt, this taut, apocalyptic thriller shows some improvement over DeJarnatt’s previous direction of Cherry 2000 (which was released in this country only on videotape), apart from some faulty continuity in the final reel. Most of the film concerns what happens when the young hero (Anthony Edwards) accidentally intercepts a phone call that announces an impending nuclear holocaust only 70 minutes away, and is desperate to find the woman (Mare Winningham) he has just fallen in love with. The action all unfolds in and around the stretch of Wilshire Boulevard that constitutes LA’s “miracle mile,” nearly all of it in the middle of the night, and the strongest B-film virtues here (apart from a running time of only 87 minutes) mainly have to do with a very nice feel for the particulars of this time, milieu, and place; the biggest drawback is that the film doesn’t wind up going anywhere in particular. Among the many interesting costars (including Lou Hancock, Danny de la Paz, Robert Doqui, Kelly Minter, and Denise Crosby), there’s a particularly nice cameo by John Agar as the heroine’s grandfather.
