Walter Keane became a national celebrity and talk show fixture in the 1950s after he pioneered the mass production of prints of big-eyed kids, and used his marketing savvy to sell them cheaply in hardware stores and gas stations across the country. Unfortunately, he claimed to be the artist. That role was played by Margaret, his shy wife. She generated the paintings from their basement and Walter's contribution was adding his signature to the bottom.
The ruse broke up their marriage, and when she tried to make it known that she authored the paintings, they ended up in a court battle after Walter called her crazy. The case culminated in a dramatic courtroom showdown. How will the truth be uncovered?
