LatchKey (2015)

'LatchKey' is a semi-improvised original series featuring improvisers from UCB, The PIT and Magnet theaters. When the Delaney kids' father passes away they want to move on with their lives and sell the apartment they grew up in. However, their childhood friends and neighbors, The Clems, (who still live together in the apartment they grew up in) aren't going to make that easy. As time passes the Delaneys realize that family may be more important than they thought and the Clems may just figure out that living with your siblings in to your 30s is creepy.
