Frank re-lives his 20s and joins the workforce for the first time!

Ian's fame in the LGBTQIA community explodes but the sudden surge of 'followers' may be more than he can handle; Frank, however, finds a way to cash in. Meanwhile, Fiona struggles with her conscience when she learns about a worker who fell off her roof and Lip realizes his relationship with Professor Youens may not have been as special as he thought.
Fiona's homeless tenants barricade themselves inside her apartment. Lip takes in a terrified Sierra and Lucas when her father is released from prison, while Ian takes bigger action with his cult- like following.
