The chase between Sylvester and Tweety continues into a busy city street, where the puddy tat himself gets chased by Hector the bulldog. All three are injured by passing cars and taken to the city hospital, where Nurse Granny tends to the threesome. Innocent Tweety is the only one who tries to get rest, but Sylvester and Hector are always at odds, kitty trying to get at the bird and doggy harassing the lisping alley cat. Sylvester tries several methods to do away with the dog, all of which fail. At one point, Sylvester does swallow Tweety, but Nurse Granny takes the cat into puddy surgery (which results in a large bandage placed over his chest). In the end, Sylvester, Tweety and Hector are released from the hospital, but the chase quickly starts again and the three wandering into traffic. "Que sera sera," sighs Granny.
