During a training session at roll call, Mac talks about the importance of "officer presence". Reed, not wanting to look like a neophyte, didn't quite understand about what the sergeant was talking and didn't want to ask, so asks Malloy after the fact, Malloy who does his best to educate his partner. On shift, Malloy and Reed attend a robbery at a gas station to find one of the clerks knocked unconscious and locked in the washroom. This call eats at Reed for the remainder of their shift if only in his naive thought that they can nab the culprit. Their next call takes them to a nursing home, where a confused elderly man insinuates himself as one of the residents despite he not being so. Their next call takes them to house where a scared teen-aged babysitter is certain a prowler is trying to break into the house. Their final call is to a suspected B&E at a warehouse. At the end of the shift, Reed believes he has a better understanding of Mac's talk based on the events of the day.
