Together- Marcus and Martinus

Astrid and Gia are best friends. At school, they are the smartest and the inseparable. If Astrid jumps off a cliff, so will Gia and everyone knows if you mess with one, you're messing with the other. Astrid seems like she's always falling into some sort of problems and Gia always has fun trying to get her out them. They meet a pair of boys from their school's foreign exchange program and they all become the perfect pair of friends from Europe. But what happens when high school starts to slowly tear Astrid apart, Gia isn't there to help, and all 4 of them aren't so "together" anymore?
