Stan works for the CIA in Langley, Virginia, and is always on the alert for terrorist activity. Stan will go to extremes to protect his beloved America from harm. Stan's son is a dorky teenager who tries to be cool and his wife has had a past life of sex and drugs. The teenage daughter of the family, currently attending community college, has turned out to be a left-wing liberal. While Stan loves his daughter, he doesn't necessarily trust her. In addition to Stan's wife and teenage children, the Smith household has two rather unconventional members: there's Roger, the sarcastic space alien who rescued Stan from area 51 and now deeply resents the fact that he's not allowed to leave the house, and therefore, has been reduced to drinking wine and smoking cigarettes... and Klaus, a lascivious, German speaking goldfish; the result of a CIA experiment gone seriously wrong where the CIA tried to give a fish a German man's brain.
