The film's screenplay is based on the book "Bắt đầu từ một kết thúc", an autobiography about the life of the ill-fated singer Wanbi Tuấn Anh.

The movie is about Dinh Phong (Son Tung M-TP) and his group of friend: Ngo Kien Ha (Ngo Kien Huy), Pham Quynh Bang (Pham Quynh Anh) whose motto is "Chả sợ gì, chỉ sợ già" (I'm afraid of nothing, aside aging), a Korean girl Sky (Hari Won) and Manager Lam (Hua Vi Van) who worships money.

Dinh Phong keeps pursuing music career after the death of his father, even dreams of having a concert on his own, however Lam forces him to become an actor.

After leaving the hospital, Lam receive a notice from the doctor informing that Dinh Phong has a cancer and is only able to live for 5 years maximum.

His mother opens crab hotpot as wishes, Lam sends all of Phong's money for children living under unfortunate condition.

However, on November 11, Galaxy Studios and WePro Entertainment, the production companies of "Dandelion" decided to delay the release date but didn't announce another official one.

Their press release stated that it was "the issue with the song "Chắc ai đó sẽ về"[3] by Sơn Tùng M-TP that led to the decision".

Director Quang Huy directly went to the movie to see the film's effects and commented, "What made me most satisfied was that almost all of the audience responses praised the cast."

[1] On Friday, January 9, 2015, Director Quang Huy confirmed total revenue of film has reached over 42 billion, after a week to the cinema .

The film has many fictitious details that offend the late singer and his late father, like Đình Phong's father eats and has a "declaration" about dog meat right on his hospital bed, or Đình Phong has an insolent attitude towards his seniors, begs kindness and compassion of the audience and colleagues to raise money for his medical treatment, which is completely different from the original version.
