明塱集团主席王进涛(钟镇涛饰)与著名心脏外科医生董一妍(宣萱饰)在欧洲举行了一场豪华婚礼,婚礼过后,进涛与两名儿子及孙儿在意外中丧生。这场悲剧让王家及集团陷入混乱,进涛的宿敌柯永成(汤镇业饰)更企图伺机夺取明塱的核心项目。同时要应付王家权力斗争及外界阴谋较量的一妍,为稳固在明塱的地位,试图拉拢进涛的两位儿媳文以珈(刘佩玥饰)和陈丽雪(吴若希饰)维持大局,然而新加入的董事方欣(陈炜饰),也对明塱虎视眈眈。而在这场权力与利益争夺战中,参与者还有带着神秘身份、与以珈有过一段情的戴德桥(陈展鹏饰)……。山田日後承認在開拍此片之前,已心諳渥美清的肺病步入末期,決定此章為最後一章,並安排由淺丘瑠璃子演的莉莉送寅次郎踏上人生的最後一程。分別15年後,兩人於如詩如畫的奄美大島重逢,感情依舊,鬥氣繼續,沒完沒了似的。正如山田所想,雖然系列必須完結,但始終不想為寅次郎的故事/人生劃上句號。結局如常開放,代表寅一直繼續他的旅程,日本人依然有夢。
公映後翌年,渥美清病逝,享年68歲,本片亦成為他的遺作。
Yamada knew before production began that Atsumi's health has deteriorated to such an extent that Tora-san to the Rescue would be the last film in the series. He decided to let Lily accompany Tora on his last trip. The lovers reunite after fifteen years in the picturesque Amami O Shima, and the affections as well as the bickering remain. Although the series must come to its conclusion, Yamada has deliberately left the film's ending open, so as not to let the curtain fall on "Tora-san". Atsumi Kiyosh passed away at the age of 68 in the year following the film's release, making this film his last.。
