What is the full name of the character who is given an executive job at Callahan auto?
After seven years at college, Thomas R. "Tommy" Callahan III barely graduates from Marquette University and returns to his hometown of Sandusky, Ohio. His father, industrialist and widower Thomas R. "Big Tom" Callahan, Jr., gives him an executive job at the family's auto parts plant, Callahan Auto. In addition to the new job and office, Big Tom reveals that he plans to marry Beverly Barrish-Burns, a woman he had met at a fat farm, and that her son Paul will become Tommy's new stepbrother, much to Tommy's delight. At the wedding, however, Big Tom suddenly dies of a heart attack. 
After the funeral, doubting the future of the company without Big Tom, the bank reneges on promises of a loan for a new brake pad division and seeks immediate payment of Callahan Auto's debts. Ray Zalinsky, owner and operator of rival automotive parts company Zalinsky Auto Parts in Chicago, offers to buy them out while the company's shares are high, but Tommy suggests a deal: he will let the bank hold his inherited shares and house in exchange for helping to sell the new brake pads. The bank agrees, but they also want the company to prove it still has viability by selling 500,000 brake pads. If they fail, the bank will foreclose, but if they succeed, the bank will underwrite Big Tom's brake pad venture. Tommy volunteers to go on a cross-country sales trip with his father's sycophantic assistant, Richard Hayden, a childhood acquaintance who has a particularly antagonistic relationship with Tommy. 
Meanwhile, Beverly and Paul are shown kissing romantically, revealing that they are not mother and son, but rather married con artists with criminal records. Paul thinks Big Tom's death is ideal, since their original plan was to eventually divorce Big Tom and take half of his estate, but Beverly thinks they are in trouble, as Big Tom only left her a controlling interest in Callahan Auto, which may evaporate. She authorizes the quick sale to Zalinsky to make a fast buck.
