While practising deep space medicine, the staff at Sector General has seen more than its fair share of challenges - from plagues caused by cafeteria food to a range of diverse ethical codes. The medics are a tough bunch - but now they face an unsettling new development: the terrifying Chief Psychologist, Dr O'Mara, has been promoted to the Head of the hospital.

But even worse - this is a temporary promotion, for just as long as it takes to train his replacement. After that, he's up for mandatory retirement. Terrifying he may be, but no one at Sector General can imagine what they will do without him - assuming they'll last long enough to find out.
