警犬马洛

自从Robby的父亲在值勤时被杀后，Robby经历了愤怒与孤独。他父亲的老搭档，警犬Marlowe也是如此。所以当Robby看到Marlowe被孤零零的锁在笼子里的时候，他请求母亲把那条狗给他。很快，他们俩就成了好朋友。但是，作为一只警犬，当Marlowe在树林里看到两个熟悉的罪犯(Robby的父亲死前正在调查的两个骗子)时，Marlowe立即开始追踪他们，直到一条繁忙的大街上。等到Robby和他最好的朋友Deb赶到时，已经太晚了，Marlowe已经被车撞倒。震惊中，Robby回到了孤寂的状态。但就在当晚，Robby听到外面有狗叫声。当他出去后，他看到了Marlowe！很快，Robby明白了这是Marlowe的鬼魂回来了，这条警犬还有案子没办完，它的新任务是帮助Robby找到两个骗子，并揭开Robby父亲死因谜团。

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 mum to let him have 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 has been hit by a speeding car. Devastated, Robby slips back into a 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 of the death of Robby's father.
