Adam and Wilfred are at the park. Wilfred is behaving petulantly. Two dog-catchers ask Wilfred if there is any reason why he isn't wearing a collar. There isn't one. The catchers regret to say that they'll have to take him into the station. Wilfred explains that he's under adult supervision - he's here with his owner's boyfriend, Adam. But Adam walks by, pretending he doesn't know Wilfred.
Wilfred is driven-off in a paddy wagon.
Adam goes home and explains to a concerned Sarah that Wilfred has been run-over and is dead. Sarah insists on seeing the body. But Adam says it was very messy and he had a mate on a farm bury it. And burn it. Sarah is devastated - but with Adam's support she can get through this.
Meanwhile, Wilfred is in the slammer and has made himself 'top dog'. He taunts the 'screws'. He is on death row: "I was a lawsuit waiting to happen." The other dogs (real dogs) help him escape with an elaborate scheme. We gain an insight into the early life of Wilfred.
Adam lies in bed at night. There is a storm outside. Lightning flashes. Wilfred's silhouette stands at the window for a second - then disappears. The next day and night, Wilfred leaves signs that he is back - taunting Adam.
Sarah makes Adam go back to the farm and get Wilfred's ashes. He returns with an urn full of someone's ashes and Sarah conducts a backyard burial ceremony. Wilfred turns up to his own funeral - and all hell breaks loose.
