Doug Kinney is a Los Angeles construction worker whose job is constantly getting in the way of his family. On one job to build a new wing of a scientific facility, Doug meets up with Dr. Leeds, a friendly scientist who has developed a successful method for cloning humans, and is introduced to Dr. Leeds' clone as proof. The scientist allows Doug to make a clone of himself that can take over for him at work, while he tries to spend some quality time with his family. The clone, called "Two", has all of Doug's memories and knowledge, but is overly macho.
