This weak sci-fi, post-disaster drama is about three people left alive after everyone else has been killed on earth. The trio is comprised of Harold (Antony Carbone), Martin (Edward Wain), and Evelyn (Betsy Jones-Moreland) who were underwater scuba diving when a mysterious glitch in the atmosphere depleted all available oxygen for a short period of time -- enough to kill off earth's population. The ambiance is at first eerie and increasingly ominous as the divers surface and slowly discover that no one is alive out there. Then the interaction of the two men with each other and with Evelyn (Eve?), takes over and the story veers into an odd romance drama as the two machos each try to seduce the last woman left on earth. The story was a first effort by scripter Robert Towne, whose muse was dozing at the moment, but was definitely back in form on later efforts (Chinatown, The Last Detail). Towne also co-starred here as Martin, using the pseudonym of Edward Wain.
