It is the year 1969 in the town of Plattsmouth, Nebraska. A mysterious mammoth dog suddenly shows up out of nowhere. Why does he become so quickly accepted into the Bozell household? Many weird events begin to occur
to both Bo and his spaced-out neighbor, Randy.
Just when things seem like they couldn't get any stranger, the dog suddenly disappears. Bo's grief is compounded by the fact that his older brother is now missing in Vietnam. Meanwhile, Matt Duncan continues to hatch his plans to exact revenge on Bo simply because Bo embarrassed him in a high school wrestling match.
