On Brooklyn Nine-Nine Season 3 Episode 6, Charles and Jake decide to take a very stressed Terry on a guys' weekend out. They head out to the cabin of a colleague expecting that he would be away, but this goes wrong. The cabin is neither as luxurious or as safe as they anticipated, they fail at fishing, and neither Jake nor Charles thought of bringing food.
Charles decides to go foraging for fungus, but falls down a sinkhole. Terry and Jake try to find him, but get lost first, and then fall into the same sinkhole. Terry and Jake then get into an argument about how Jake doesn't take responsibility for anything.
Jake takes this to heart, and finds a way out of the pit while the others are sleeping. Terry later realizes that he really does need to relax, and finds a fun way to do so.
Holt realizes that Rosa is planning on breaking up with Marcus, and advises her to break up with him via text message. They later realize that this may not be the best approach, and Rosa practices the break-up on Captain Holt.
She breaks up with Marcus, but finds herself getting emotional afterwards. Holt tries to be supportive, but suffers the same emotional fate.
Amy wants to sell her reader-flashlight idea to the powers that be, but realizes that she may be too boring to do so. She asks Gina to help her spice up her presentation to make a better impression. The presentation is a success, but her bosses do not go for the flashlight. Gina later encourages Amy by showing her how she made a difference.
