The aftermath of a shooting in one of the high schools in Brno where the rules bordering on bullying are set by members of a floor hockey team and their groupies – a girl gang called Bitchez. In ten episodes, Czech Television’s first original streaming series tells the story of a search for boundaries in the painful world of teenagers manipulated by social media. It is targeted primarily at teen audiences. The title, TBH, is an acronym which stands for „to be honest” in online slang. It has, however, taken on a different meaning since it was adopted by teens – to mask a lie or alter the truth. The series is based on the results of a survey conducted among the target group in selected schools. The director worked in cooperation with a writing team of students from the Film School in Prague.
