Ty Davis becomes a policeman like his father and Carlos becomes a paramedic. The two recruits work with older, wiser partners. Carlos works with the serious Monty "Doc" Parker and Ty works with John "Sully" Sullivan, his father's old partner. Meanwhile paramedics Bobby and Kim rush from emergency to emergency; officers Bosco and Yokas and firefighter Jimmy have other problems to deal with.

The "feud" between Doherty and Bosco escalates; a watch's owner is sought.
