The trailer opens with a grand music concert, with a sparkling stage and thousands of spectators. Immediately after that, the image of the white sand hill appeared opposite to the sun, wind, and the dryness of the dragon bones.
In another detail, Mr. Phuoc is also a father who wants his children to have stability in their university studies, while his eldest son - Tam wants to conquer the dream of becoming an idol. And to make his dream come true, Tam and his group of friends together formed the band "The Light" and submitted a song to compete in a major music competition - Hi Idols!
The trailer also first introduced the humorous appearance of director Ly Hai as Mr. Long - the owner of the parking lot, and the typical floral motif. Witnessing the mind and group of friends practicing, Mr. Long as well as many people in the village, no one believed The Light will overcome the "parking" round, or achieve achievements at Hi Idols! Because of that, for Mr. Phuoc, the fact that Tam really wants to develop professionally on the music path is even more difficult to accept.
Not only focusing on Tam's family, director Ly Hai also exploited the stories of other members in "The Light". Each family, each situation, but the way of giving advice to their children is completely different. Not opposing Mr. Phuoc and Mrs. Hien, Le's family is blind to their mother but loves their children very much. Although Le is wondering about her dream of becoming a celebrity, for Le's mother, why can't her children...


And after many speculations, Le Tuan Khang appeared in the trailer with a role that seemed to "time the steering wheel" for him - a motorbike taxi driver who graduated from the University of Science and Technology, majoring in mechanical engineering.
Besides Le Tuan Khang, Meritorious Artist Chieu Xuan has made initial revelations for his role in Lat mat 8. In the scene where Mr. Phuoc tries to get a bus to the city, he received help from the characters of Le Tuan Khang and Meritorious Artist Chieu Xuan.
In the official trailer, the differences between the generations in the family is even more shown. The character of her grandmother is often thought to be "the person of the previous generation" who understands and supports the most dreams of the two grandchildren.
In particular, once again in the trailer, the image of war in coconut forest was recreated in the memory of her grandmother. The longer reminiscent of Ly Hai's dedication and crew for this scene. The scene of real explosion shows the fierce war, when the life of people is more fragile than ever.
The cast participating in Lat mat 8 includes: Meritorious Artist Kim Phuong, Meritorious Artist Huu Chau, Meritorious Artist Tuyet Thu, Meritorious Artist Chieu Xuan, Ngan Quynh, Kieu Trinh, Long Dep Trai, Quach Ngoc Tuyen...
The film was officially opened for sale from April 18.
