Ever since Robby’s father was killed while on police duty, Robby has been angry and
alone. His father’s old partner, a police dog named Marlowe, suffers the same fate. So when Robby sees Marlowe alone and locked up in a cage he begs his mom to keep him. Instantly, the two are best friends. But, being a cop dog, when Marlowe sees two familiar criminals in the woods, (the same two crooks Robby’s father was investigating when he died) Marlowe immediately chases them—right into a busy street. By the time Robby and his best friend, Deb, catch up, it’s too late—Marlowe had been hit by a speeding car. Devastated, Robby slips back into his reclusive state. But later that night, Robby hears barking outside. When he goes to investigate, he sees Marlowe.
Soon, Robby learns Marlowe has come back as a ghost. The cop dog has unfinished
business to take care of. His new mission is to help Robby find the two crooks and
solve the mystery behind the death of Robby’s father.
