Hi,

I once saw a movie (fantasy genre) with a bunch (around 5) teenagers (8 to 15 years I would guess) who went into an old hotel (it was sealed for years already) and in the underground sewer pipeline they discovered an old pirate treasure. It contained a bottle with a speaking plug on top. One of the children took a piece of the treasure and afterwards the plug came of and released a monster that hunts on them. They tried to lock the monster in a vault, but it escaped (let the vault melt). At the end it appeared that one of the children was an descendant of the master of the monster/ghost that had to protect the treasure...
Anyone know the name of this movie?

Thanks already!
