Synopsis:
On vacation from school, Linda Lee visits Clark Kent at the Daily Planet and nearly gives away his secret identity. After she is scolded, Linda accepts a job as a summer camp counselor. While watching over the children, she finds evidence that one of the campers has discovered her secret identity. Supergirl tries to discover which girl found out, but fails. She then flies to Superman's Fortress where a Red Kryptonite detector informs her that she was exposed. The Red K has caused her to covertly betray her own secret identity. Fortunately no one else discovered the evidence, so Supergirl's secret is not revealed.
