Kelly and Evan have had it with new the tenants upstairs (Adam, Lucy and Nikki). If they're not hogging the communal washing machine, then they're monopolising the hot water system.

High proximity equals high tension, with communication breakdowns happening in all corners. When the tenants discover they are sharing Orlando's fleas, Kelly declares war!
