9 to 5

On the first day of the secretary Judy Bernly at the Consolidated Companies, the senior office supervisor Violet Newstead is in charge to introduce her to the coworkers. Judy was a housewife that has never worked but after her recent divorce, she is forced to find a job. Violet explains that their boss Franklin Hart Jr. is a sexist, egotistical, lying, hypocritical bigot and his secretary Doralee Rhodes is his mistress. When Violet develops a method to increase the profit of the company, the opportunist Franklin backstabs Violet and presents the wok as if he had made it. Later the chauvinist Franklin does not promote Violet. He also spreads rumors about Doralee and mistreats Judy. When Violet accidentally put rat poison in Franklin's coffee, he has an accident with his chair, hits his head on the floor, loses consciousness and drops his coffee on the floor. He goes to the hospital and Violet and her friends believe he had died. When Franklin returns to the office, his snitch learns what happened and he blackmails the secretaries that kidnap him. Now Violet administrates the office with Judy and Doralee and they discover that Franklin is stealing Consolidated Companies. How can they prove?
