To a family whose children are traumatized by the death of their mother, help comes in a most bizarre way.

They go to a bizarre factory, where they customize their new grandmother, and within a short time, she arrives. The android is equipped with everything needed as a parent and the boys are charmed. The daughter, however, still misses her mother and she bears no welcome for this interloper.
