Plot 
A blue and white collie dog named Jacob is driven by his owner to a forest in South Korea where he is released and abandoned.

Jacob waits for his owner to return. While waiting, he is discovered by a pack of stray dogs consisting of two chihuahuas wearing vests, a German Shepherd named Tony, and their leader, a small scruffy dog named Alex. They inform Jacob that his owner won't return which he finds hard to believe until the conversation is interrupted by a car parking nearby, leaving a scrawny crippled dog on the roadside and driving away. Jacob is mortified and begins to believe that he too has been abandoned. The strays carry the new crippled dog with them into a human town; there Jacob encounters the local dogcatcher but makes a narrow escape with the help of another town stray named Eddie, and they return to the Strays' home inside a dilapidated abandoned building. They discuss their living conditions with the dangers of the doghunter and Tony mentions a distant paradise they could travel to by scent, only to be shot down by Alex.

The following day the strays travel to a nearby restaurant where a friendly chef is known to feed the dogs. There Jacob sees a human he mistakes for his owner and chases them into the restaurant only to be hastily driven from the building. That night as Jacob lies awake the sickly dog begins moving; she asks Jacob to bring her to her mom and then collapses. The following morning she is found to have passed away. The dogs bury her in the buildings dirt yard along with other past graves where they gather and mourn; Jacob leaves to disown his tennis ball into a river.

Jacob witnesses a pack of wild dogs hunting a boar and running off into the mountains. The pack consists of a black dog named Kelley, a pair named Shirley and Edward, and their son Trevin. They return to their den site where they discuss the recent lack of prey due to humans and their fear of human settlements. That day the town strays find that the friendly chef was fired for attracting stray dogs and they are no longer welcome.

The next day Jacob goes to visit the wild dogs where he meets Trevin and follows him to their den site. He hopes to make friends with them with a bone as a gift, only to be told that town strays don't belong with wild dogs and sent back to town. That night Eddie is captured by the dog catcher and the stray town dogs again debate their living conditions. Tony mentions the potential paradise he vaguely remembers and Jacob mentions living in the mountains like the wild dogs, but Alex chastises Jacob's criticism of their lifestyle. Jacob runs off and hopes to impress the wild dogs by driving goats from a human farm into the mountains for them to kill and eat, only for Edward to chastise him for endangering them by angering the humans. As expected, the goat farmer calls animal control services for the wild dogs resulting in Jacob and Trevin being captured and put into a pound. Jacob is injected with a GPS tracking chip with intent on later using him to locate the other stray dogs. 

Jacob recalls his childhood in a puppy mill where he was separated from his mother and siblings to be sold in a pet store, where he was adopted by a family who were unaware of how large he would grow. That night he, Trevin and all other captive dogs are freed from the pound by the wild dogs. As they flee they discuss their need for a new home and Jacob recalls the paradise Tony mentions. The town dog's abandoned building is destroyed by human construction and they too need a new home. Together they and the wild dogs agree to follow Tony to the land he remembers.

The dogs cross a highway, but Shirley and Edward are killed by a car collision. The dogs find that the fields on the other side make safe living grounds and successfully hunt a deer together. Kelley tells Jacob about her childhood in a puppy mill where dogs are abused until disposed of and how her mother was taken when she became too ill; Kelley was almost doomed to the same life but managed to escape, ending up with the wild dogs.

The strays' newfound peace is shortlived as the doghunters find them using Jacob's tracking device, but the dogs narrowly escape in a wildfire. Along their journey they encounter a household of friendly humans who rescue injured animals and have several crippled dogs. Jacob attempts to leave the others due to suspecting the tracking chip in his neck but Kelley refuses to allow it. They encounter the doghunter whom they defeat in a fight and leave in the middle of the forest. Alex decides that he will stay with the humans and they make their goodbyes before the strays continue their journey.

The strays arrive at the border of the Korean Demilitarized Zone and see the paradise they've been seeking on the other side of the barbed fence wall. Tony recalls he was once a guard dog here. The stray dogs escape through the gate into the wilderness on the otherside except for Jacob, who gets stuck behind. After being chased around by the military personnel, Jacob leaps over the wall and escapes with the strays into the peaceful, uninhabited wilderness.
