Hoops & Yoyo can't wait for Halloween... but they have waited until the last minute to begin their search for costumes. When that search leads them to the mall, they are accidentally locked inside after closing. They discover that this favorite daytime haunt is actually haunted at night. But through a series of frightening events, they learn that "monsters" aren't always who they seem to be.

'Evolution of Evil' is the story of Lori and Christopher, a Pacific Northwest couple wanting to get away from the hustle and bustle of the city into the wilderness. The couple makes their way past the usual campsites, and backpack into the remote Mt. Hood Wilderness area.
