Shell Quiz, known in its latest iteration as Shell Quiz on the Road, is a televised upper-secondary school quiz competition in Thailand which was broadcast from 1965 to 2009. The questions are given in English, and deal with a broad range of topics of knowledge, with the English language itself as a focus. The programme was sponsored by Shell Thailand. At the time of its last season, it was the longest-running television programme in the country.
"Grean" is Thai slang for a yet not mature youth, coming from the style of haircut common to young men at school. The film followed the final years of high school of several teenagers interested in the arts and in film production up until their university entrance exams. The series continues where the film left off, with the students growing up and growing into college life and adulthood.
Will they enter college? How will they continue their film production? Will they work with Pramote and his studio, which he sets up for them: Grean House? The series is a comedy promising to focus not so much on teen issues as on the meaning of being an adult.
