Deep End

 The pool has been closed for years. Tonight, nobody is getting out. 

Six graduating seniors have one final prank planned before leaving Riverside High behind: sneak into the abandoned natatorium, release five hundred rubber ducks into the pool, hang a ridiculous banner, and get out before anyone notices.

It should be the perfect ending to their high school years.

But someone is already inside.

The doors lock. Their phones become useless. Strange sounds echo through the empty locker rooms, and the building's long-abandoned equipment begins operating on its own.

Then one of them disappears.

Three years earlier, a freshman named Jonathan Vega drowned in that same swimming pool during a cruel initiation ritual. His death was ruled an accident, and the people who knew what happened went on with their lives.

Someone hasn't forgotten.

Now the six teenagers are trapped inside a building where every corridor leads to another danger, every secret brings a new accusation, and a figure wearing an old diving helmet is determined to make them pay.

As the night turns deadly, the survivors must uncover what really happened to Jonathan before the person hunting them finishes what he started.

 Because some high school pranks are unforgettable. This one is unforgivable. 

 DEEP END is a dark psychological horror thriller about bullying, buried secrets, and a senior prank that becomes a fight for survival.
