游泳欣人如其名，热爱游泳，父亲游山年轻时是飞鱼，因此她立志成为游泳国手，努力苦练，但比赛时她往往因紧张而游不出佳绩，屡战屡败，但乐观的她依旧勇往直前。泳欣两岁时，母亲忽不告而别，游山从此性情大变，过着招摇撞骗的生活。幸好泳欣有前队友夫妇欧英雄与白娜娜照顾，两人有一个当帆船教练的儿子欧耀阳，泳欣暗恋他，并视他为偶像崇拜。
泳欣偶遇拉大提琴的王宇乐，对音乐一窍不通的泳欣不禁陶醉在他的音乐当中。宇乐的父亲很支持儿子追求音乐的理想，但因母亲王若云是黑市夫人，所以在父亲猝逝后，母子便陷入困境，被逼住进三房式组屋，并和泳欣成了邻居。游山受不了宇乐练习大提琴时的干扰，与王若云不时斗气，而泳欣也无法忍受宇乐是个生活白痴，百忙中常抽空去帮他们做家务。
从国外回来的Fei加入泳队，Fei属天才型泳手，成绩斐然，泳欣因此鞭策自己更加努力。Fei有一个热爱帆船运动的弟弟陈方，而教练就是耀阳。Fei自视甚高，但和耀阳接触后，开始对他有了好感，主动接近。
Fei的母亲Yvonne在泳会出现，原来她就是泳欣失踪二十年的妈妈。Yvonne在接触泳欣的过程中，建立了感情。泳欣也发现Yvonne是自己的亲生母亲，Yvonne竟佯称当年是遭游山遗弃，造成泳欣对游山有所误解。英雄看不过眼，说出Yvonne抛夫弃女的所作所为，泳欣得知真相后，因感怀身世而变得无心训练。此时宇乐陪在泳欣身边，拉琴帮她排解压力，让泳欣重新站了起来。
宇乐开始融入组屋生活，但是女友许嘉宜却很不自在。这时好朋友Thunder从国外回来，Thunder在演奏界小有名气，让宇乐觉得自己成就不如他，因此更加日夜苦练。善于制造惊喜的Thunder，更是让嘉宜有些意乱情迷。宇乐不忍母亲辛苦赚钱养家，终放下尊严，到高级酒廊演奏，意志却逐渐消沉。泳欣发现宇乐的琴声似乎少了以往的感情，为了鼓励宇乐，说出自己永远都会是他的忠实听众，宇乐受到鼓舞，振作起来。
宇乐发现嘉宜移情别恋，横刀夺爱的是自己的好友Thunder，他一时无法接受事实，还因此意外导致暂时失聪。一连串的打击再度把宇乐击倒了。泳欣以自己的经历来勉励宇乐。游山和王若云也放下宿怨，一起帮助宇乐熬过难关。
耀阳和Fei日久生情，他竟想脚踏两船。得知耀阳背着自己和Fei交往，泳欣难以接受，失去动力，游泳成绩更加不理想，她开始考虑是否放弃自己最喜欢的游泳。Fei也不满耀阳对待感情不认真，提出分手，耀阳落得两头空。
Yvonne看中泳会的地皮，提出收购献议。董事们觉得泳会多年来栽培不出国手，同意卖地，英雄夫妇大力反对。Yvonne得知耀阳陷入商业失信罪，意图利用金钱诱使耀阳支持出让泳会，但耀阳不为所动。Fei痛心Yvonne的不择手段，不惜和她反目。泳欣对游泳的热忱再度被激起，她联合Fei，与董事们达成协议，只要在泳赛赢得锦标，泳会就获得保留。Yvonne百般阻挠，游山重出江湖，将自己的经验倾囊相授，泳欣和Fei是否能够排除万难，突破自己，争取佳绩，成功抢救泳会？
宇乐终了解到学习音乐，最重要的是享受过程，放下压力的他心情变得放松，与此同时他却接获知名乐团的邀请函，终于当上演奏家。正当泳欣和宇乐有所发展之际，嘉宜和Thunder的感情游戏也宣告终止，嘉宜想要重投宇乐怀抱...
泳欣再度跳下泳池，因为只有游泳能让自己无拘无束，摆脱一切的烦恼...，Fei和耀阳再次相遇，两人是否能够重续旧缘...！
You Yongxin, as her name suggests, is an avid swimmer. She is determined to become a national swimmer like her father, You Shan, who was helmed as the "flying fish" in his swimming days. Yet, no matter how hard Yongxin trains, she still underperforms at competitions due to nervousness. Despite numerous failures, the ever-optimistic Yongxin remains steadfast in achieving her dream.
When Yongxin was two years old, her mother walked out on the family. Since then, You Shan became a changed man - he began to lead the life of a conman. Fortunately, You Shan's former teammate, Ou Yingxiong and his wife, Bai Nana, took Yongxin under their wing. The couple has a son, Ou Yaoyang, who is a sailing coach. Yongxin not only idolizes Yaoyang but is also secretly in love with him.
Meeting cellist Wang Yule in a chanced encounter left Yongxin, who knows nothing about music, completely mesmerized by his music. Yule's father was very supportive of his music career but when his father passed away suddenly, he and his mother were plunged into financial difficulties as his mother, Wang Ruoyun, was his father's mistress. They were forced to move into a 3-room HDB flat and thus, became neighbors with Yongxin. Disturbed by Yule's cello practices, You Shan often finds himself at loggerheads with Wang Ruoyun. In spite of her hectic schedule, Yongxin takes time off to help the Wangs with their housework as Yule knows nothing about it.
Fei has just returned from abroad and joins the swimming team. Naturally gifted, Fei chalks up impressive results in the pool, which made Yongxin train herself even harder. Fei's younger brother, Chen Fang, is a sailing enthusiast who trains under Yaoyang. Fei, who thinks highly of herself, finds herself attracted to Yaoyang and takes the initiative to get close to him.
Fei's mother, Yvonne, shows up at the swimming club. She is Yongxin's biological mother who had vanished 20 years ago. After coming into contact with Yongxin, Yvonne developed kindred feeling towards her. When Yongxin realizes that Yvonne is her mother, the latter claims she was abandoned by You Shan. As a result, Yongxin gets the wrong idea about her father. Yingxiong sets the record straight by pointing out that it was Yvonne who walked out on them instead. Troubled by her family background, Yongxin is not able to concentrate on her training. Yule helped Yongxin to get back on her feet by playing the cello for her and staying by her side.
Yule adapts to living in a HDB flat but his girlfriend, Xu Jiayi, feels out of place. Yule's good friend, Thunder, returns from overseas, having made a name for himself as a music conductor. Not wanting to be outshined by Thunder's success, Yule trains even harder. Jiayi gradually finds herself attracted to Thunder as the latter is full of surprises. Seeing how hard his mother works for the family, Yule decided to put aside his pride and performs at a high-class lounge to ease his mother's burden. However, he soon becomes despondent. Yongxin noticed that Yule's cello playing has become emotionally detached. To encourage him, Yongxin reveals that she will always be his devoted listener. Heartened, Yule braces up.
Yule discovers that Jiayi has shifted her affections to another man and that man is none other than Thunder, his good friend. As a result of his inability to accept the truth, Yule loses his hearing temporarily. Yule collapses after being dealt with one blow after another. Yongxin relates her own experience to motivate Yule. Even their parents, You Shan and Wang Ruoyun, put aside their differences to help Yule tide over the crisis.
Yaoyang and Fei developed feelings for each other over time. Yaoyang hopes to have his cake and eat it too by two-timing Fei and Yongxin. Yongxin loses her motivation to swim as she is unable to accept Yaoyang seeing Fei behind her back. You Shan is arrested by the police for fraud again. Mentally and physically exhausted, Yongxin loses her motivation to swim. In the face of her dismal results, Yongxin considers giving up swimming. Seeing how he treats matters of the heart so frivolously, Fei breaks up with Yaoyang, who ends up losing both girls.
Yvonne eyes the plot of land on which the swimming club stands and makes an offer for it. With not a single national swimmer produced after all these years, the board of directors agreed to the sale while Yingxiong and his wife vehemently opposed.
Yvonne sets Yaoyang up, causing him to commit criminal breach of trust. He is forced to convince his parents to support the sale of the land. Deeply hurt by her mother's unscrupulousness, Fei falls out with Yvonne. Yongxin's passion for swimming rekindled and together with Fei, they joined forces to save the swimming club. They made an agreement with the board - the swimming club will not be sold if the swimming club wins the championship title. With Yvonne setting up all kinds of obstacles in their way, will Yongxin and Fei be able to overcome and rise above the challenges to successfully save the swimming club?
Yule finally realized that enjoying the process of learning is the most important aspect of music. Having learnt to let go of the past, Yule becomes more relaxed. At the same time, he receives an invitation from a renowned orchestra and finally attains his goal of being a music conductor. Just as love is blossoming between Yule and Yongxin, Jiayi and Thunder ends their relationship. Jiayi hopes to return to Yule.
As only swimming can help her forget her troubles, Yongxin returns to the pool once again. Fei and Yaoyang bumps into each other, will they be able to re-kindle their romance?
