TVI's (Television International) Senior Manager of the account department Lam Siu-siu (Teresa Mo) meets TVI's Director of the production department Koo Hiu-san (Wayne Lai), when he calls her into a meeting to explain why none of his requested work equipment has been approved for budget. Siu-siu calmly explains that due to his assistant Tong Chong-shu's (Mark Ma), multiple errors in filing the paperwork, miss of deadline to resubmit before the fiscal quarter ends and unresolved department invoices the account department will not approve any new budget request. Hiu-san, who has a reputation for being a mean boss demands to have the issue resolved right away but Siu-siu tells him to schedule another meeting with her as it is 5:45 pm and time for her to get off work. Unimpressed with her reason to end the meeting, Hiu-san mocks Siu-siu for leaving work at 5:45 pm. However Hiu-san's comments backfires when Siu-siu mocks him back by hinting that his department is unorganized and then telling him the available executive secretary in his department has been unfilled for so long because he is difficult and no one wants to work for him.
Hiu-san finds a way for Siu-siu to voluntarily resolve his department's invoice issues when he hints that her best friend and TVI's hairstyles Chiu Lei-hung's (Angela Tong), job might be on line. Ever since then Siu-siu assumes Hiu-san is bias against her and wants to get back at her for insulting him at their earlier meeting. Lei-hung, who is an unruly worker and slacker changes her work ethics knowing that she might be out of a job soon. Seeing how Hiu-san got Lei-hung to change, Siu-siu ask him for advice to handle Lei-hung since her unemployed make-up artist uncle who lives with her Lam Yi-mak (Power Chan), has a similar personality to Lei-hung. Siu-siu learns that Hiu-san does have a softer side when she coincidentally meets his father Koo Lik-hang (Chung King-fai) after losing her cellular phone.
Siu-siu gets tricked by her co-worker to transfer out of the accounting department when she thinks someone will be fired because of company budget issues. Due to her kindness to her co-worker she volunteers to leave the accounting department and interviews for all available positions within TVI, even Hiu-san's longtime unfilled executive secretary position. During her interview Siu-siu does not expect Hiu-san to hire her because of their past clashes so she gives an honest opinion about him and his department during her interview. Siu-siu is devastated when she finds out her co-worker had played her for a fool in order to oust her from the accounting department to get promoted as the new head of the accounting department, but her day however ends on a high note when Hiu-San offers her the executive secretary position and lets her know her salary will be higher then what she is currently making in accounting.
