Charlie visits the hospital due to some issues he’s been having with mild chest pains. He meets Dave and is given an opportunity to shadow him for a few days, in hopes of eventually pursuing his own career in medicine. However, a medical emergency thrusts Charlie into an unexpected situation, leading him to rush to save someone’s life with barely any training or experience.

A gentleman named Kevin visits the hospital for a routine dental appointment, but Anthony at first does not realize he is actually his biological father. Upon learning each other’s names and talking with each other about life, they make the discovery simultaneously and Kevin insists on getting to know his long-lost son. Will Anthony continue to hesitate, or grow to understand his father and welcome him into his life?

After suffering a severe toothache, Charlie asks Anthony to evaluate and fix the problem. This, in turn, leads to him revealing his fear of dental procedures, specifically those involving the use of a drill, so Anthony decides to take him on as his assistant to help him grow more comfortable with the equipment. But, of course, something has to go wrong and Charlie has to learn to conquer his fears in the most frightening way possible.

The team gets reassigned as paramedics due to a staff shortage. They meet the lead paramedic and get trained for emergency medical services in less than a week. Will they be able to handle the faster pace of ambulance work?

Due to a recent string of patients coming in with an unknown illness, the hospital laboratory asks for help in their research from Charlie, Kevin and Dave. Will they be able to find out what’s affecting all of Rockport, and come up with a cure to save the city?

Charlie wonders if medicine really is the right career path for him, so he decides to explore other opportunities and chooses to train to be a police officer. Intrigued by this new challenge, Anthony decides to join him at the academy. However, it soon becomes clear that being a cop isn’t just about coffee and donuts.

Inspired by his son’s recent graduation from the police academy, Kevin signs up himself… only to find out the hard way he may not be cut out to be a cop after all. Will Anthony (with Charlie’s help) be able to whip his dad into shape, or will Kevin continue being… Kevin?

Charlie and Anthony receive a promotion at the police department… to the S.W.A.T. team! Not only that, but thanks to their heroic efforts of the past, they are assigned as squad leaders. But one day, their leadership—and tactical skills—will be put to the ultimate test.

PART 1: Charlie decides to enlist in the Army, much to everyone’s surprise. And despite his own feelings about the situation, Anthony makes the difficult choice to enlist along with him, to ensure his safety and protect his best friend. They enter Boot Camp at Fort Braxton together, and find it’s a lot harder than both of them thought. Will they push through the adversity and complete their training, or will they give up before it gets even worse?

PART 2: After a rigorous and tough Boot Camp, Charlie and Anthony find out they’re being deployed to Afghanistan the following week. They ensure all their affairs are in order (including Anthony asking Kevin to step in as a dentist while he’s away, and trying to give him months of training in just a few days) then head overseas. While there, they meet their very strict general and get caught up in a blindside attack that leads to a grave situation towards the end.

PART 3: Charlie is seriously injured during an ambush and is brought to the base medical center for treatment. Anthony sees that he’s being treated by a doctor who clearly doesn’t want any part in his care, so he finds an opportunity to step in and take charge himself, then discovers Charlie’s injuries are worse than everyone first thought. Will he be able to save his canine friend before it’s too late?

PART 4: In the aftermath of the ambush, Anthony discovers that Charlie has disappeared during their recovery, then finds out it could be a case of desertion. Despite him being injured, he insists on being involved with finding Charlie himself, and through his best efforts tries to track him down. Will he find his best friend before the MPs do, and will he have the guts to bring him to justice?

Charlie is arrested by Anthony for his prior crime of desertion and sentenced to serve time at Carson State Penitentiary. He has a difficult time adapting to prison life, and finds himself constantly mocked, bullied, and ridiculed during his time there. Will Charlie be able to survive the system?

Anthony brings Charlie back to the Army medical center in Afghanistan, and they begin their work as combat medics (and dentists) for the base. They encounter several patients they have to treat and start getting overwhelmed. Will they be able to handle the pressure of their new positions?

After returning to Rockport, Charlie decides he wants to become a firedog… even though he’s not a Dalmatian. But, as expected, he gets way more than he bargained for.

Anthony learns he has to fly back to Denver to receive operations on his eyes, and would be gone for approximately six months. While on the plane ride there, trouble begins brewing and it’s up to him to save the day once again… this time, with no help.
