Struggling to make ends meet, Gardner finds himself and his five-year-old son evicted from their San Francisco apartment with nowhere to go.

Chris Gardner (Will Smith) is a family man struggling to make ends meet. Despite his valiant attempts to help keep the family afloat, the mother (Thandie Newton) of his five-year-old son Christopher (Jaden Christopher Syre Smith) is buckling under the constant strain of financial pressure. No longer able to cope, she reluctantly decides to leave.

Chris, now a single father, continues doggedly to pursue a better-paying job using every sales skill he knows. He lands an internship at a prestigious stock brokerage firm, and although there is no salary, he accepts, hopeful he will end the program with a job and a promising future. Without a financial cushion, Chris and his son are soon evicted from their apartment and forced to sleep in shelters, bus stations, bathrooms, or wherever they can find refuge for the night.

Despite his troubles, Chris continues to honor his commitment as a loving and caring father, using the affection and trust his son has placed in him as an impetus to overcome the obstacles he faces.
