Matron runs Haven Hospital with a rod of iron. One ward sister and her nurses, however, look set for quite a bumpy ride...
For starters, there's champion boxer Bernie Bishop, in with a broken wrist inflicted when delivering a knockout blow, and not too pleased by the length of his enforced stay; private patient The Colonel, in a side room of his own, who's a gambling obsessive; nuclear physics student Oliver Reckitt, who is far from amused by distractions from his study; Jack Bell, sick of the long wait for a mere bunion removal; and Ted York, a journalist suffering from appendicitis who swiftly falls for the beautiful Nurse Denton.
As each man waits for his recuperation or procedure to be carried out, tensions begin to rise - and it's not long before fellow patients are giving Bell a hand to get out of hospital before he misses a romantic get-away!
