Doctor's Disorders (S02E02)

After a swarm of tiny green ghost beetles infects them, the students of Casper High develop unusual ghostly abilities and are isolated in a creepy old hospital on the outskirts of town. Determined to uncover the truth, Danny sneaks into the facility but is soon caught by Penelope Spectra and her aide, Bertrand. They orchestrated the outbreak to create a stunning new body for Penelope, requiring Danny's unique half-human, half-ghost DNA to succeed. With Danny imprisoned and Sam falling ill, Tucker must overcome his hospital phobia to rescue his friend before Penelope achieves her sinister goal.
