After failing to return a demon-possessed teenage girl to her parents, Stroker and Hoop decide to help a high school marching band find out who has been sending the band threatening letters, and stole the money from their fund raising car wash.

Meanwhile, C.A.R.R. develops an addiction to car washes, and abandons Stroker and Hoop when they are ambushed by a goon squad of mascots, to go on a car washing binge.
