Plot:
A school bus of teen girls are heading on a trip to an archeological site.
On the road, the brothers, Pete and Al are trying to fix their motorcycles when Jay, the truly good-guy, stops
to help them. They decide to ride together for a while. Passing the bus, the girls are waving and flirting.

Of course, neither of us are crazed psycho-killer bikers that only make a cheap movie plot...
By random luck, all stop at the gas station.Jay meets with one of the girls before the bus heads out. The gas
atttendant takes care of the bikes. Al stays behind a little for when the attendant goes under a car, he
lets the jack loose which causes the car to crush the attendant to death.
The bus breaks down several miles down the road. Marv the driver isn't able to get it fixed. A couple of the
girls break out to cat-fight because that's genetically required in 1970s b-movies.

Well, this one time in band camp....
Pete, Al, and Jay pull up. Al and Pete can't fix the bike. Mis Tenney, the teacher, asks if they go and call for
help. She refuses to let any of the girls go with the guys.
The bikers haul the bus to a nearby deserted farm. Al and Pete keep threatening to leave them there and drive
off. Miss Tenney takes enough until Al slaps her. The brothers chase Marv around before running over him.

Who knew bikers would think that jumping over school bus
drivers would be so exciting>
Al is getting terrified of the idea of going to back to jail and need to eliminate all the witnesses.
Jay realizes that the brothers might go after them but hopes they just ride off.
That night, in the farmhouse, the girls are sitting around terrified. When Al wants for Bobbie, one of the
girls, to "entertain" him, Miss Tenney and Jay stop it. Al drags Miss Tenney into another room and attacks her
before the ominous music plays for a worse attack.
Pete ties Jay up. Bobbie distracts Pete so Judy can untie Jay who manages to run away for help. Jay hops on
his bike and is chased by Pete who is able to ram Jay off a 60 foot cliff.

You'd have escaped me if you hadn't spent all that time
putting on your helmet...
Back at the farm, Al is acting more and more deranged. Miss Tenney tells Tina, the mousy girl, to escape and
go for help. The brothers realize that Tina has escaped. Al chases, catches, and strangles her. That night Al
returns to the farm. Pete is boozing heavier.
The next morning, Pete steps out of the farm when a noose is dropped around his neck. It's Jay who hangs
him. Al walks out and the final fight begins. Al versus Jay. Miss Tenney grabsa steel rod and impales
Al.
Later, Jay rides off for help. Miss Tenney and the girls hug in 1970s style as the credits roll.
