See Spot Run

A drug-sniffing canine becomes the target of an assassin boss, prompting the FBI to deploy Witness Protection to relocate him. Meanwhile, a single mom entrusts her six-year-old son James to her unreliable, mailman neighbor Gordon after the babysitter bails. An assassin mob boss hires two goons to kill Agent 11. But when 11 escapes from the van during the attempt, he hides in Gordon's mail truck, where James is also present. And guess what they name him: Spot.
