The spectral PHANTOM is haunting the museum and is after a rare skull that will boost his powers. Not so fast, THUNDERGIRL ( KITTY DANGER ) is on the job and is determined to put an end to his supernatural crime spree. But it appears our heroine is no match for his ghostly powers and is soon subdued. The PHANTOM plans to dispatch T-GIRL once and for all using the museum's own CHAMBER OF HORRORS . He soon has our plucky superheroine tied down to a stone slab under a razor sharp swinging pendulum. Can THUNDERGIRL escape and foil the evil PHANTOM or she about to become sliced bread???
