Avery and Hazel weren't just normal people. They are in-between ghosts. And no, not the scary ones from the dumb horror movies. Think of them more of a Casper the friendly ghost, but more of a teenage version who doesn't always act as friendly as Casper. These in-between ghosts are able to stay on earth as long as they don't give out the secret that they are still around. In-between ghosts also have special powers. This power can range from flying to getting into human's heads. Everything is fine while Avery and Hazel are staying in an abandoned house, until Dylan and Tyler, a pair of best friends move into their territory. The girl's first instinct is to run, but not this time. They need to teach people that Avery and Hazel aren't just going to roll over for the humans. Will this plan backfire on them? One thing is for sure... They aren't like you and I.
