David E. Talbert makes his directorial debut with this comedy about Durell (Ice Cube) and LeeJohn (Tracy Morgan), childhood friends with a knack for getting into trouble. Despite his continual bad decisions, Durell gets one thing right: he's a good father to his adolescent son. When he learns that the boy's mother, his ex-girlfriend, Omunique (Regina Hall), needs $17,000 to buy her beauty shop or she'll leave Baltimore and move to Atlanta, he's determined to get her the money to keep his son in his life. Meanwhile, LeeJohn needs big money fast to pay off some bad guys. Durell and LeeJohn decide that the collection plate of their local church holds the answer to their money woes. But their attempt to rob the church is foiled in progress: the money is already missing, and the would-be burglars didn't realize there would be people at the church. Finding themselves with a group of parishioners and choir members at their mercy, Durell and LeeJohn have to make some decisions about exactly what kind of men they want to be.
FIRST SUNDAY also makes a statement about the role of the church in urban areas and its importance within the community. Keith David is Deacon Randy, who has grandiose plans for moving the church to a "less urban" neighborhood. Chi McBride stars as Pastor Mitchell, and Malinda Williams is his strong-willed daughter, Tianna, who wants First Hope Community Church to stay right where it is and expand its services. Loretta Devine is Sister Doris, the parish secretary and foster mother with a heart of gold. Ice Cube and Morgan have good rapport as the bickering buddies, with Morgan's silliness providing loads of comic relief, but Katt Williams is the scene-stealer as Rickey, the flamboyant choir director with something to say about everything and everyone.
