Synopsis
Fong Hok Man (方學文 - Paul Chun 秦 沛) is a bookeeper at an old fashioned bookstore. Being old enough to retire, he doesn't wish to purely for his love of reading. He met his wife Yu Yok (顏如玉 - Mary Hon 韓馬利) by chance at a bookstore, falling in love over shared love for books and eventually got married. Because of this, Hok Man has an even bigger emotional link. Fong Sum Ming (方心明 - Wayne Lai 黎耀祥), their eldest son, is sensible and family-minded. After completing Form 5 decided to work and earn a living to help reduce his parents load. Their second son Fong Sum Ching (方心正 - Eric Suen 孫耀威) is intelligent, with excellent academic results. His ambition had been to go to the US to continue his studies attending college. Coincidentally, an uncle running a factory in Mauritius was recruiting HK people. Without needing any specialist training and paying wages much higher than in HK, Sum Ming saw this opportunity and decided to go for it, enabling him to send money back home every month and get his brother into college. After many years working in Mauritius,the factory closed down and Sum Ching had graduated, leaving Sum Ming with no responsibilites and the decision to return to HK. Knowing times had changed, he decided to broaden his career options, taking lessons and courses and becomes a security guard.
方學文是一間舊式書店的老臣子，將屆退休之齡，不言退休的他原因是特別鍾愛看書，是名符其實的書迷。文、史、哲，甚至武俠小說都是學文所好，還喜歡不時向親友推介十本好書，希望每個人都能培養出讀書的興趣。他與妻子顏如玉都是在書店邂逅，志趣相投，繼而發展成夫妻，因此書店於他有著極深厚的情義結。
大兒子方心明孝順生性，中五畢業後便決定打工賺錢，以幫輕父母的擔子。同時看見二弟方心正聰明伶俐，讀書成績好，願望是到美國繼續大學課程讀大學，剛巧在毛里裘斯設廠的細叔伯欲聘請香港人到當地當管工，不需要甚麼專門技術，但工資比香港時高出數千元，心明覺是一個賺錢的好機會，便決定漂洋過海工作去，知慳識儉地每月寄錢回家支持心正到美國升學。
心正回港工作在毛里裘斯工作了十多年的心明，工廠面臨結業，同時眼見二弟心正讀書有成，已了無負擔，遂決定回香港。他深知與香港的生活總有點脫節，工廠大多已北移，因此打算轉型其它方面的工作，報讀普通話、考保安牌、的士牌等等…心明都用心去學去考，最後當上個保安員。至於心正方面，在美國完成大學課程之後，成為出色的網絡保安工程師。剛巧獵頭公司為香港一間大機構以高薪厚職招攬心正，心正對這份工作蠻感興趣，同時又可以回香港與家人團聚，可以說是一舉兩得，於是決定回香港發展。
心明是初級物業保安，心正則是網絡高級保安工程師，同樣稱之為保安，但兩份職業可說是有很大分別。心正不但事業有成，還有一位乖巧賢淑的好女友雷婉儀。小女兒心美還是個中六學生，有著時下年青人的習性，整日沉迷上網，打機，與網友chat，因而引發起一連串的家庭小風波…
家人互相關懷有一間舊書店的老闆年紀老大，子女又不願繼承衣砵，打算結業，適時學文見心明任職保安員，前景不表樂觀，為提升心明社會地位，毅然決定按樓，傾盡所有作頂手費，為心明舖路，他日接手書店做老闆。後來，心明得悉父親心意，既感動又慚愧，幾經掙扎，最終辭退保安員一職，替學文打理書店。自小少看書，多看漫畫的心明，如今接觸書本多了，竟看出點點興趣來，看在老父學文眼中，是最值得欣喜的事。
心正因為工作的關係，與同事徐希敏投契非常，事業如日方中。此時，女友婉儀主動提出分手，更避走美國，心正唯有寄情工作，與希敏合作無間，情愫漸生。家人眼見心正失戀多時，感情終於有著落，亦感欣慰。後來，婉儀回歸，心正夾在舊愛新歡之間，左右做人難。但因感情事局外人難以插手，家人們只能默默支持心正，作出他以為最恰當的選擇。
