A group of young Internship (medicine) join the City Hospital surgery staff run by Dr. Prang, a brash and cynical surgeon leading an expensive and dissolute lifestyle. Meanwhile, old American Mafia Sal Bonafetti is admitted to the same hospital under an assumed name after suffering a stroke; his son Angelo cross-dressing in order to tend to Sal, fearing retaliation by rival crime syndicates. Professional hitman Malamud is admitted to a bed next to Sal's in order to assassinate him, but his every attempt fails, causing Malamud himself to undergo painful and unnecessary treatment.
