Franco Mars was a French Exchange student who came to Grange Park High School, where he was relentlessly bullied by Mack Taylor, Tre Brown, 'Scally' Blackwood and Remy Ahmed. This affected Franco so badly that he tried to jump off the school roof in a suicide bid three days before he was due to go back to France. The teachers at Grange Park tried to get Taylor and his gang arrested for the bullying, but could not gather enough evidence. Mars eventually returned to his home country, although later than planned.
