In the Wahlberg house, 5 o'clock is always dinnertime. When Donnie brings girlfriend Jenny McCarthy home to meet his mother, Jenny falls in love with Alma's famous tomato sauce. Troublemaker Donnie decides to stir the pot by instigating a "sauce-off" between Ma and Paul. As the competition heats up, Paul also has his hands full creating a special "Burger of the Month" for Jenny. With Mark as the deciding vote, who will win the Wahlberg's first annual sauce competition?

When Paul takes the day off work to play a round of golf with Mark, he leaves their mother, Alma, in charge of the day shift at their second restaurant "Alma Nove" -- much to her delight. As Paul and Mark talk business and engage in their usual game of brotherly harassment, Alma uses her newfound position to finally make a few changes to the restaurant without Paul's interference.
