Colorized version of Larry, Moe and Curly are working at a hospital ""For duty and humanity"". They respond to each call only to find the hospital has a few more nuts than expected, from a man who sees things to a nurse with the hiccups. Later, their boss is in need of surgery to get the combination of a safe out, so the boys decide to operate. Comedy ensues through every mode of transportation, every glass broken, and every response from the PA system.
