三个刚退休，迎来的却是被儿女、家人无视的大叔。

在一场家庭世代争执后，大叔们为了让年轻世代认真关注自己的存在价值，端正社会风气，发扬职人精神，而跑去当网红。

他们将在这段旅程中当歌手，发专辑，变成唱跳男团，跳洗脑舞，与00后屁孩辩论人生真意，找初恋一起高空弹跳，当一日市长，还完成粉丝的梦想……

并且告诉社会大众，谁说60岁不能有梦想！

可是他们要对抗的，不是只有他们眼中的小屁孩，真正要对抗的，其实是自己已经日薄西山的体力，还有自带的高血压，糖尿病⋯⋯

The three retired middle-aged men have been ignored by their children and family.

After a fall-out with their family, they become internet celebrities to prove themselves to the younger generation, promote social integrity and carry forward the craftsmanship.

During the journey, they try to be singers with their own album, singing and dancing, to debate with youngsters about the true meanings of life, a bungee jump with first love, to be a one-day mayor and to realize the dreams of their fans… Also, they try to tell people that a 60-something man can have his own dreams!

However, they need to fight against not only those youngsters, but also their declining strength, high blood pressure, diabetes…
