Ethan's efforts to avoid Alicia prove futile when the pair are dispatched to rescue a professor and her son after they fell into a cave while out jogging. As the pair descend into the fissure by winch, debris begins to fall, and sparks fly as Ethan tries to reassure a claustrophobia Alicia. Meanwhile, Louise is disheartened when the trust denies her funds for a new relatives' room, so Noel helps her to seek donations from the public, and one of Holby's cleaners takes a tumble while trying to leave the hospital with a set of suspiciously full bags.
