The Pursuit of Happyness (2006) on Netflix

1981, San Francisco. In what limited academic opportunities he has had in his life, Chris Gardner has demonstrated that he is a smart man. Yet he is struggling financially in his life. He has invested all his money on portable bone density scanners, which he personally sells to physicians. Despite being a better product than x-rays machines, they are also far more expensive, meaning that they are an unnecessary luxury for most physicians. He needs to sell three scanners per month just to meet the basic necessities to support his family, his wife, Linda, and their five year old son, Christopher, on who he dotes since he didn't know his own father when he was a child. But lately, that has been three per month more than he has sold, resulting in an increasing embittered Linda continually needing to work double shifts doing manual work at a laundry, which still isn't enough to cover those basic costs, they being currently behind three months rent. Chris can't afford to pay his parking ticket, meaning that he has to take the bus everywhere now as the clamp remains on the tire of his car. Feeling like the scanner is not the answer to their financial problems, Chris, with or without Linda's blessing, decides to take a chance by switching careers when he sees that brokerage and securities firm Dean Witter has a six month internship program, which only admits twenty applicants, leading to only one intern being hired at the end of the process. It isn't until he is well immersed into the process that he learns that the internships are non-paying. Based largely on his chutzpah, Chris, against the odds, gets one of the twenty positions. With some changes in their lives resulting in fewer expenses, Chris figures he needs to sell his remaining six scanners just to scrape by for those six months. But some unexpected issues arise which leads to the Gardners possibly not making it through this phase of their lives financially, something he has to hide from his superiors at Dean Witter if he has any chance at all of making it through the internship and getting that paying job with them.
