Howard Beale, the longtime anchor of the Union Broadcasting System's UBS Evening News, learns from his friend and the news division president, Max Schumacher, that he has just two more weeks on the air because of declining ratings. The two get drunk and lament the state of their industry. The following night, Beale announces on live television that he will commit suicide on next Tuesday's broadcast. UBS fires him after this incident, but Schumacher intervenes so that Beale can have a dignified farewell. Beale promises he will apologize for his outburst, but once on the air, he launches back into a rant claiming that life is "bullshit". Beale's outburst causes the newscast's ratings to spike, and much to Schumacher's dismay, the upper echelons of UBS decide to exploit Beale's antics rather than pull him off the air. In one impassioned diatribe, Beale galvanizes the nation, persuading his viewers to shout out of their windows "I'm as mad as hell, and I'm not going to take this anymore!"
Diana Christensen heads the network's programming department; seeking just one hit show, she cuts a deal with a band of radical terrorists (a parody of the Symbionese Liberation Army called the "Ecumenical Liberation Army"[citation needed]) for a new docudrama series called The Mao Tse-Tung Hour for the upcoming fall season. When Beale's ratings seem to have topped out, Christensen approaches Schumacher and offers to help him "develop" the news show. He says no to the professional offer, but not to the personal one, and the two begin an affair. When Schumacher decides to end Beale as the "Angry Man" format, Christensen convinces her boss, Frank Hackett, to slot the evening news show under the entertainment division so she can develop it. Hackett agrees, bullying the UBS executives to consent and firing Schumacher. Soon afterward, Beale is hosting a new program called The Howard Beale Show, top-billed as "the mad prophet of the airwaves". Ultimately, the show becomes the most highly rated program on television, and Beale finds new celebrity preaching his angry message in front of a live studio audience that, on cue, chants Beale's signature catchphrase en masse: "We're as mad as hell, and we're not going to take this anymore." At first, Max and Diana's romance withers as the show flourishes, but in the flush of high ratings, the two ultimately find their way back together, and Schumacher leaves his wife of over 25 years for Christensen. But Christensen's fanatical devotion to her job and emotional emptiness ultimately drive Max back to try returning to his wife, even though he doesn't think she'll agree, and he warns his former lover that she will self-destruct at the pace she is running with her career. "You are television incarnate, Diana," he tells her, "indifferent to suffering, insensitive to joy. All of life is reduced to the common rubble of banality."
When Beale discovers that Communications Corporation of America (CCA), the conglomerate that owns UBS, will be bought out by an even larger Saudi Arabian conglomerate, he launches an on-screen tirade against the deal, encouraging viewers to send telegrams to the White House telling them, "I want the CCA deal stopped now!" This throws the top network brass into a state of panic because the company's debt load has made merger essential for survival. Hackett takes Beale to meet with CCA chairman Arthur Jensen, who explicates his own "corporate cosmology" to Beale, describing the interrelatedness of the participants in the international economy and the illusory nature of nationality distinctions. Jensen persuades Beale to abandon the populist messages and preach his new "evangel". However, television audiences find his new sermons on the dehumanization of society depressing, and ratings begin to slide, yet Jensen will not allow UBS executives to fire Beale. Seeing its two-for-the-price-of-one valueâsolving the Beale problem plus sparking a boost in season-opener ratingsâChristensen, Hackett, and the other executives decide to hire the Ecumenical Liberation Army to assassinate Beale on the air. The assassination succeeds, putting an end to The Howard Beale Show and kicking off a second season of The Mao Tse-Tung Hour.
