When a new bar opens in the neighborhood, it completes the final piece of the puzzle for Nick’s epic Valentine’s Day pub crawl. Meanwhile, Jess and Ryan drunkenly contemplate their future, Coach meets a new woman – over and over again – and Schmidt tries to fit into the world of politics.

While shopping for baby diapers for Sue, who has run out of them on a baby-sitting job, Frankie is completely humiliated when a clerk assumes she's shopping for adult diapers. Meanwhile, after getting on Mike's case to get a physical exam because she thinks men tend to fall apart faster than women as they age, Frankie proceeds to throw out her back and hides it from Mike, who tells her he received a clean bill of health from the doctor; a clueless Sue falls for Axl's friend Sean, who barely notices her existence; and Brick begins to test all of the age-old urban legends parents tell their kids – such as not to swallow a watermelon seed for fear one will grow in their belly – after discovering Frankie has used these white lies on him in the past.

John teaches Ben several key tips to being a police officer, including the proper ways to make a death notification and arrest a suspected drug user. Sammy stays with Nate's family while he sorts out his marital problems. Lydia and Josie handle a drug-related murder case with an unorthodox suspect.

Lydia dons a uniform and hits the streets when the shift is short a supervisor and she must fill in. Meanwhile, John and Jessica are stuck with a film crew tagging along on their calls. Elsewhere, Ben infuriates Sammy when he implies Sammy planted evidence.

Record breaking heat sends the night shift team and their patients into a frenzy.
