**SPOILERS** Movie about a Love Canal like town, Landry Texas, thats about to explode with long buried toxins seeping out of the ground and effecting everyone there, man and animal alike,through the water supply as well as the air itself.
After a young boy was found dead at the bottom of a shaft on the Buckhurst Industries site the owners of the company went all out to prevent the truth from coming out. The Buckhurst bigwigs going to meet in secret at a hotel room in L.A to plan their next move are spied on and their talk tape recorded by electricians Mike Newman and his partner Doug, Dale Robinette & Kane Holiday.
Thinking that their getting the goods on some guy cheating on his wife, for a defective agency that they have a contract with, the two electricians instead overhear a plan by the businessmen to cover up their unsavory actions over the years. They plan in having the entire town of Landry blown up by staging an accident for a tractor-trailer loaded with the deadly chemical agent 10-45T. The deadly chemical was a secret agent that was used by the US military in Vietnam and at the same time was buried in and around Landry by the truckload, as they drove by the Brockhurst factory site.
With dozens of people in the and around Landry starting to come down with fatal illnesses it's only a matter of time when it's discovered that that chemical was buried there and those responsible, Brockhurst Industries, will be sued into bankruptcy. The conspirators accidentally, through a glass of red wine where they can see the electricians laser, find out that there's some kind of laser device being beamed on the hotel room. The Brockhurst group then get two of their paid hit men out to find where the beam is coming from, and to shut up those responsible for it for good, and retrieve the audio tape.
After a half hour car chase through the city the hit men track down Mike and Doug to Mike's home where they murder Doug and, after a ferocious fight, finish off Mike but they can't find the incriminating tape of their boss' conversation at the hotel.
The Buckhurst gang now get after the late Mike Newman's wife singer Brooke Newman, Lynda Carter,who hid with her young daughter in terror from them in a closet and who they think has the tape. The fact is that Brooke does know about the tape but she doesn't know just where it is and it's a lot closer to her then to the hit men now looking for it.
Standered plot about corruption and murder in corporate America, circa 1980, with leggy and frisky, not to mention beautiful, Lynda Carter as singer housewife private investigator and now action hero, or heroine. Lynda not only plays detective to break the case wide open but also flies up and down the friendly, and unfriendly, skies of Texas with helicopter pilot Sid Pachanski, Ronny Fox. Lynda & Sid try to get the jump on the bad guys before they turn Lawery Texas, by causing a tractor-trailer truck loaded with the deadly 10-45T to explode, into what Chernobyl in the Ukraine turned out to be some six years later in 1986: uninhabitable.
Besides being the reluctant heroine, at first all Brooke wanted to do is get out of town with her young daughter, Brooke also had a chance to sing the title song "The Last Song" in the film.
