Does this sound like what may have happened at the Oroville Dam in California, USA?
From the Simpsons Season 8 Episode 16 Aired on : February 23rd, 1997. Exactly 20 years ago as i post this video.
Plot: Former criminal Sideshow Bob is declared a changed man by Reverend Lovejoy and released from prison on a work program, despite the protests of Bart. Bob is surprised to be taken into the care of his brother Cecil as the two had previously not spoken for ten years. A flashback reveals the cause of this rift: Cecil had auditioned to become the new sidekick for Krusty the Clown, a job he had long desired, but Bob, who had not originally intended to be the sidekick, was chosen instead. Cecil, who is Springfield’s chief hydrological and hydrodynamical engineer, employs Bob to supervise the construction of a hydroelectric dam in a river near Springfield, while Bart, believing that Bob is still evil, continuously follows him around. Bob begins to become intensely annoyed by Bart’s intrusions into his personal life and the dam’s incompetent laborers (Cletus and his family), and he expresses a desire to see the dam burst and obliterate Springfield.
Meanwhile, Bart enlists Lisa to help find out what Sideshow Bob is up to, but only ends up being discovered rummaging in Bob’s trash and angrily escorted home by him. They finally decide to search in Bob’s trailer at the dam construction site, and discover a briefcase full of cash. On being interrupted by Bob, the children run and hide inside the dam’s turbine room, but are cornered. When confronted with the money, Bob denies knowing anything about it, stating that he’s putting up his finances to build the dam walls out of concrete, but is distraught to see the walls empty and poorly constructed. The kids then believe that Bob is cutting back on construction materials by embezzling the money for himself, but Cecil shows up with a gun and reveals that he is the one who embezzled the money; now he plans on framing Bob and using him as a scapegoat when the poorly constructed dam collapses. He officially declares his greed of the money motivated him to enact his plan, though he privately admits to Bob that his true motivation was because of Bob being chosen as Krusty’s sidekick instead of Cecil. Without hesitation, Cecil locks Bob, Bart and Lisa in the dam and prepares to blow it up, taking the money with him…
