Doug Kinney has a demanding construction job, which doesn’t leave him much time for his family, much less for himself. He feels frustrated and his wife is always nagging about him not helping out with the kids. On one of his jobs Doug meets Dr. Owen Leeds, a geneticist. Dr. Leeds interests Doug to become the ultimate split personality by having himself cloned. He begins slowly with only one clone, Doug #2, to take care of his job in order for Doug #1 to have more leisure time. That wasn’t enough, he clones himself again, creating Doug #3 to take care of Laura and the kids. Well, Doug #2 and #3 get bored so they clone Doug #2 to make Doug #4. That was a big mistake because a copy from a copy just isn’t as good. Doug’s life was complicated before, but now it is almost out of control since instead of being in charge of just one Doug, he is now in charge of FOUR Dougs!

Doug #1 has been on an overnight sailing trip without his family or his clones. He had left Doug #3 in charge hoping to find his family still in order when he returned. Instead, he finds Doug #2, #3, and #4 siting on his couch. He’s shocked because he didn’t want Laura to find out that he had himself cloned. Doug #2 is quick to inform him that Laura will never find out because she left. While Doug #1 was gone, Laura had come into contact with all three clones and each one responded to her conversations in different ways since none knew what the other had said to her before. She becomes angry and frustrated, takes the kids and stays with her mother. Not only that, but Doug #2 got fired from Doug #1’s job. Doug #1 tells them that they have ruined his life and Doug #2 informs him that they are all the same person so inevitably Doug #1 ruined his own life. Unknowingly, Doug #1 gave himself another future.
