Teen comedy double. Lindsay Lohan stars in the survival-of-the-fittest comedy 'Mean Girls' (2004) as Cady Heron, a pretty 15-year-old who has spent most of her life in the wilds of Africa being home-schooled by her zoologist parents. Her upbringing has taught her a lot about survival in the wilderness and the subtleties of animal behaviour, but nothing she has learned can prepare her for the unspoken social etiquette of a mid-American high school, where jocks, cheerleaders, stoners and cool kids jostle for popularity, and a clique of rich and popular girls known as 'the Plastics' rule the school. This group of alpha females, led by 'professional life-ruiner' Regina George (Rachel McAdams), is initially contemptuous of Cady but then accepts her as a new member. Cady, who in the meantime has become friends with punky misfits Janis and Damian, starts to get close to the 'mean girls', initially out of curiosity - but it isn't long before she's enjoying the buzz of being one of the most popular girls in the school. However, when she inadvertently crosses the line by going on a date with one of Regina's ex-boyfriends, the gorgeous Aaron (Jonathan Bennett), the Plastics go on the warpath, and Cady must pay for her initiation into their mean Plastic world. In the made-for-television sequel 'Mean Girls 2' (2011), 17-year-old tomboy Jo Mitchell (Meaghan Jette Martin) moves to a new school where she befriends fellow social outcast Abby Hanover (Jennifer Stone), and together they take on the 'Plastics', led by uber mean girl Mandi Weatherly (Maiara Walsh).
