 On its way to Azati Prime, Enterprise has to pass a region of reconfigured space which will be harmful to the human crew. In order to avoid the dangerous effects, Dr. Phlox advises to put the entire crew in a coma, instead of a taking a too long flight around the reconfigured space. On the 4 days journey, Phlox will assume command of the ship, as he is not affected. Barely underway, he starts hearing some strange sounds.
