A school trip brings the boys to a practice archaeological dig. They look for Indian arrowheads, but Cartman finds a triangle with arcane symbols. He gets sick of it and throws it away, leaving Kyle to pick it up.
None other than Barbara Streisand takes note of the event. The popular chanteuse wants the item for a different purpose: it will be the vital part yet missing from a device that could unleash deadly magical powers.
When the diamond is assembled, it will give Streisand the ability to transform herself into a giant robotic monster, with strength not stoppable by conventional means.
There's only one thing to do.
The crew call on Robert Smith, lead singer of alternative rock legends The Cure, who uses his own mystical means to become the counterpart that can defeat Streisand.
Will the world be saved? Will the boys live to hear their favorite album again?
Tune in and find out. Satirical lunacy as only the kids of this tiny mountain town can bring it.
