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.
