My plot synopsis

The Phonecall

It was a saturday night, and a bunch of us from college were at a house party somewhere out of town. It was around half past eleven when people started leaving to head home.  About five of us stayed behind, we were all going to rent a movie and just chill out for the rest of the evening. We all got the pillows and duvets from upstairs and put them in front of the t.v ready. We started to tidy the place up a bit first, chucking all the empty bottles that had just been left everywhere into black bags, as we were doing this one of the boys began to tell us about a rumour that had been going round, about a group of college kids who went missing one night whilst camping up by the lakeside. Apparently, someone kept trying to contact them all from an unknown number at midnight but no one knows what was said during the calls or what happened after.
It all went quiet for a moment and then we all just broke into bursts of laughter and continued to tidy the place up, I looked at the clock, it was almost midnight already. So we finished the tidying and all settled down to watch the movie. The phone rang, "I'll get it" Laura shouted. "Hmm, that's weird, no one answered, I could just hear someone breathing down the phone. Must of got the wrong number or something. I'll just go and take this bag out to the road side".
The rest of us cosied up in front of the t.v and started playing the movie.
About 20 minutes had passed and Laura still hadn't come back in.
"Guys, where's Laura, she's been ages, she only went to take the rubbish bag out to the road side".
"She's probably come in without us noticing and has gone to the loo or something" said Nick.
"She's been 25 minutes! "
The phone started to ring again.
"Dont worry, i'll get that and i'll pop out to see what Laura's up to" said Nick. 
"Oh, there was no reply again, must be something wrong with the phone lines. I'll just see what Laura's doing then". And he slammed the door behind him.
I went to sit with the other two in the living room and tried watching the film, but i couldnt help but think, something weird was going on, but i sat watching the film, waiting for them to come back through the front door.
Again 20 minutes had passed and there was still no sign of Laura or Nick.
"Guys, just wait here a sec, im just going to pop out the front and see what's going on".
I walked down the drive, down towards the road, I could see the rubbish bag placed at the end of the drive, but there was no sign of them. I walked down until the end of the drive, I looked down, I could see drops of blood leading down the drive and along side the road. My mobile phone began to ring in my pocket, it was an unkown number. I answered, someone was there but didnt say a word. There was just breathing down the phone...
