House and the team take on the case of a ballerina whose lungs collapse in the middle of a performance. When the treatment causes her skin to fall off, the dancer faces not only the prospect of never dancing again but also of dying an agonizing death. The team must use their imaginations to carefully choreograph ways to test and treat her delicate body without killing her. Meanwhile, House continues to suffer from what he thinks is insomnia, and he is willing to go to desperate measures to cure it.
