It's tough making ends meet for Brenda (ANGELA BASSETT), a single mom trying to raise her three kids -- talented high school basketball player Michael (LANCE GROSS) and his younger sisters Tosha (CHLOE BAILEY) and Lena (MARIANA TOLBERT) -- in the Chicago projects where they live.
Michael's biological father, Michael, Sr. (PHILLIP EDWARD VAN LEAR), a construction worker, is of no help as he refuses to pay child support. Things get worse for Brenda and her outspoken friend and coworker, Cheryl (SOFIA VERGARA), when the plant they work in abruptly shuts down, and then when the electric company shuts off Brenda's power.
Even so, she tries to be the best mom she can, even when there's barely enough food to get by and no money for daycare. All of which means she doesn't want Michael hanging out with his drug dealer friend Calvin (KRISTOPHER LOFTON), and blows off former pro basketball player and current scout Harry (RICK FOX) when he comes knocking, interested in Michael and his on-court talent.
Brenda's life would seem to hit its nadir when she receives news that her father has passed away. Yet, the fact that she never knew or even met the man results in that development not even making her top list of lifelong disappointments. Even so, Cheryl convinces her that she should go to the funeral in the off chance that something was left for her in the will.
Thus, Brenda packs up the kids and heads for a small town in Georgia where they meet her father's other family, the Browns. They include her half-siblings Sarah (MARGARET AVERY) and her husband L.B. (FRANKIE FAISON); rancorous, highly opinionated and functioning alcoholic Vera (JENIFER LEWIS) and her gynecologist son Will (LAMMAN RUCKER); the outrageous in dress and behavior LeRoy Brown (DAVID MANN) who's prone to spewing one malapropism after another; and his widowed, single mom daughter, Cora (TAMELA MANN).
To her surprise, Brenda also runs into Harry once again, as he knows the family and lives nearby. Cautious about all men after being burned too many times in her life, she blows off his romantic overtures, but reluctantly allows him to help mentor Michael's basketball future. From that point on, Brenda tries to do what's right for her kids, all while dealing with an extended family she never knew she had.
