Jerry and Elaine travel to Florida to see Jerry's parents which they soon regret when Elaine injures her back on a fold - out couch and Jerry gets caught up in a scandal by just saying that he liked someone's pen.

Jerry is investigated by the library for a book he checked out in 1971 and never returned. Elaine fears for her career when her boss hates her recommendations, and Kramer strikes up a relationship with the librarian. Meanwhile, George believes that a homeless man is his old gym teacher, whom he got fired.
