It is a comic reimagining of the Watergate scandal which ended the presidency of Richard Nixon and features several cast members from Saturday Night Live and The Kids in the Hall.
On the night of the Watergate break-in, the girls sneak out of Arlene's home to mail a letter to enter a contest to win a date with teen idol singer Bobby Sherman.
On these visits they accidentally influence major events such as the Vietnam peace process and the Nixon–Brezhnev accord, by bringing along cookies that they have inadvertently baked marijuana into.
Later, when Betsy's brother, Larry, reveals the cookies' "secret ingredient" and hears the President ate them, he concludes that this explains Nixon's paranoia.
The girls become familiar with the Nixon administration's key players, including Henry Kissinger, and accidentally learn the major secrets of the Watergate scandal.
They now reevaluate what they have learned and decide to reveal everything to the "radical muckraking bastards" (Nixon's words) at The Washington Post, Bob Woodward and Carl Bernstein.
So they become informants: two 15-year-old girls are the true identity of the famous Deep Throat (Betsy's brother had just been caught watching the film of the same name).
To make matters worse, their only piece of physical evidence, a list of names of those involved from the Committee to Re-Elect the President, is eaten by Betsy's dog.
Following his resignation, as his helicopter flies over Betsy's house, the girls hold up a sign with the phrase "You suck, Dick", further angering the now ex-president.
Fleming said that he was surprised at the attempts to rehabilitate Nixon's image, and Longin cited the Watergate scandal as a defining political moment for their generation.
[4] Sony's marketing research indicated teenage girls were the film's biggest demographic, so promotional material focused on Dunst and Williams instead of the political aspects.
The website's critics consensus reads, "A clever, funny slice of alternate history, Dick farcically re-imagines the Watergate era and largely succeeds, thanks to quirky, winning performances from Michelle Williams, Kirsten Dunst and Will Ferrell.
Led Zeppelin's "Over the Hills and Far Away" was originally intended to accompany the closing scene, but Fleming eventually realized Carly Simon's "You're So Vain" was a better fit and used it instead.
