[1] It revolves around the eponymous character, a canine facsimile of Dangerfield owned by a Las Vegas showgirl, who gets dumped off the Hoover Dam and finds himself living on a farm.

Rover Dangerfield is a Basset Hound living the life of luxury in Las Vegas with his owner Connie, a showgirl.

One night, he sees Connie's duplicitous boyfriend Rocky negotiating with a pair of gangsters, and accidentally disrupts it by dropping a bone into the meeting.

In retaliation for ruining his deal, Rocky stuffs Rover in a bag, drives him to Hoover Dam and throws him into the water.

Infuriated, Rocky tries to retaliate, but Rover and friends chase him out of the casino, where he is beckoned into the gangsters' limo, presumably taken to be thrown off the Hoover Dam.

Understanding that he misses his new life, Connie takes Rover back to the farm to stay, allowing Cal and Danny to keep him.
