Is there a grammar rule behind the hyphen in the phrase 'one-act play'?

Okay, so it might sound like a primitive question. However, I can find out a reasoning or maybe which form is correct.

The sentence is

This is a three parts series.

I'm not sure if I should add the delimiter or not; and maybe there is a possession "'s", and I'm not quite sure of that. So any help with explanation would be great!

There is no possession. Unless it's your three-part series. – yoozer8 Jun 26 '12 at 1:22

I would write it like this:

This is a three-part series.

No s, with a hyphen. As for why, when you put a compound adjectival phrase (like three-part) in front of a noun, you hyphenate it.
