Detective Scott Turner has three days left in the local police department before he moves to a bigger city to get some 'real' cases—not just misdemeanors. When Amos Reed is murdered, Scott sets himself on the case, but the closest thing to a witness to the murder is Reed's dog, Hooch, which Scott has to take care of—to avoid Hooch being 'put to sleep'.

Tom Hanks makes Turner and Hooch more entertaining than it might look on paper, but ultimately, this is still a deeply silly comedy about a cop and a canine.
