Wow.. is an episode or what..??
It just started with all of the characters line up like a schoolroom day one...
Oh... I see this is your 1st time...
Well... welcome to the life of a writer...
The 1st step is the hardest, now that you passed that... it will be easier from now on...
I think that you can write whatever you want, it doesn't matter if your plot will be similar to anybody else..
Cuz when I read the many many books that are out there... most of their plots are also similar to each other in some way or another...
Good luck and happy writing na jaaa!!!
