Ernie is still living with the Ricardos, much to their annoyance. The Ricardos and Mertzes try different schemes to get Ernie to leave on his own accord.

The Ricardos are taking a summer trip to Maine after Ricky's band is booked there, so they sublet their apartment for the summer. After the booking is canceled, the Ricardos need their apartment back, but the subtenant refuses to leave.
