<human>: Hi everyone, first time posting here and I'm coming to your help as you guys are my last chance of making this one out .

So it all began on 27 nov in my sport class at which I arrived 5 minutes late and I wasn't allowed to enter . Togheter with 2 other friends and one that captured the moment, we jumped out the window and over a small fence  that separates the school from the actual gym class . All in all we didn't mean any harm to our highschool and we just went back inside the school and waited there for the next class . 

A few days later this video has been made public and got to a pretty popular Facebook page . I tried contacting the person who posted it (he wasn't even from our group of friends) and the admins of the page but with no succes .

Unfortunately, as we expected, the headmaster found out about this video and is now threatening us with expulsion . Knowing that we didn't mean any of this and was just an inside joke, no teachers were involve and it's just a small portion of the school that shows in the clip is there any method that we can pull this on trough ?

Can you summarize the given text in a few sentences?
<bot>: We tried to escape from our gym class by jumping trough the windows and over a fence, we got filmed by another coleague and the headmaster found out about it . How to we settle this down ?
