During a heat wave, Dave accidentally knocks out power to the Butler home with his drone, forcing Calvin and Tina to stay at the Johnson home to keep cool. While preparing to sleep that night, Calvin finds Dave's journal and reads an insulting entry about himself, causing a rift between the two. Meanwhile, Malcolm stays at Marty's apartment and pulls a prank by rearranging all of Marty's beloved collections, but Malcolm gets his comeuppance at work the next day.

With REO Speedwagon in town for a concert, Calvin is delighted that Dave likes the band so that he can take Tina in Calvin's place. When someone mistakes Dave and Tina for a married couple at the show, Tina laughs and says that could never happen, hurting Dave's feelings. She tells him they are just too different, and she's not talking about color. At home, Calvin and Malcolm try to help Gemma rid her house of a wild parrot that flew in. Meanwhile, Marty scares Grover as they watch a meteor shower, saying that one could hit the earth at any time and cause a major catastrophe.
