I guess the way the promo is it gives the impression it's another film attacking him, but the title states what the film is doing. It's going back to square one where all the mess started to show Michael was extorted and it does so with people who were there in the lawyer's office conjuring up ways to get Michael to pay money. The legal clerk who worked with the law firm allegedly states Jordan Chandler was in the office being coached and that for this particular client the lawyer did all calls or meetings in hiding or behind closed doors unlike his other cases as if they wanted no witnesses to know what they were really planning. It even states how the father drugged his son to get him to make a confession.
It also has audio of the father admitting he was going after Michael for money(in addition to the audio that was online for years where he admits he was going to ruin MJ). The film also explains how the civil case where Michael paid the money(which they say he didn't want to) was messed up because it left his defense strategy opened up for the criminal case(which was the real plan of the civil case) which ended up not happening because they didn't have enough evidence to go to court(they tried to find other kids who would admit Michael molested them, but couldn't to add to the Chandler case). The legal clerk explains that people just assume that the civil case and pay out excused Michael from the criminal case, but the two had nothing to do with each other.
Square One tries to show that if the original case was a straight extortion than the following accusations may be questionable as well because the original accusation is what changed people's perception of Michael which allowed following accusations to seem credible.
