The Pursuit of Happyness
In 1981, San Francisco salesman Chris Gardner invests his entire life savings in portable bone density scanners, which he demonstrates to doctors and pitches as a handy quantum leap over standard X-rays. The scanners play a vital role in his life. While he is able to sell most of them, the time lag between the sales and his growing financial demands enrage his already alienated wife Linda, who works as a hotel maid. The financial instability increasingly erodes their marriage, in spite of them caring for Christopher Jr., their soon-to-be five-year-old son. Because Chris has trouble selling the scanners, as they only produce a slightly better picture than a common X-ray but for a much higher price, and hence does not have enough money to make ends meet, Linda has to work double shifts.
