Two suburban parents and their children are traumatized by an evil spiritual force in the new trailer for indie horror flick Insidious. It's got all the makings of a classic scare flick: creepy know-it-all old ladies, evil baby monitors, Darth Maul demons, and even creepier kids.

And here's a teaser trailer with some new scenes from a few months back.

Here's the official synopsis:

A family looks to prevent evil spirits from trapping their comatose child in a realm called The Further.

What, pray tell is this "The Further" and does this mean that the call is coming from inside the kid?

Insidious will be in theaters on April 1st.
