PHILADELPHIA - An upcoming episode of "Dinner Impossible," the Food Network's version of a culinary "Mission: Impossible," will feature Psi Upsilon fraternity brothers from the University of Pennsylvania doing their part to create a feast for Penn President Amy Gutmann and guests.

Scheduled to air at 10:30 p.m., Wednesday, April 18, the half-hour show will be rebroadcast at 1:30 a.m., Thursday, April 19; 4:30 p.m. and 11:30 p.m., Sunday, April 22; and 2:30 a.m., Monday, April 23.

More than 20 fraternity brothers volunteered to take part in the show, in which celebrity chef Robert Irvine is dropped into an unknown culinary challenge, with no food or supplies and his only staff -- in this case -- a group of college men.  

The episode is set in the Psi Upsilon fraternity house, a.k.a. The Castle, a 19th century stone building that overlooks College Green in the middle of Penn's campus.  While its baronial living room is spacious enough for the president's dinner for 60, its tiny kitchen is in the basement, at the end of a long, dark hallway and has  a broken dumb waiter and gas stove with few working burners.

As an added element to the challenge, some of Philadelphia's best-known chefs and restaurateurs are among the invited dinner guests, which also includes fraternity alumni and Penn administrators.

The chef and his volunteer crew must figure out how to create a five-course gourmet meal in fewer than 10 hours.  Do they meet the challenge or is "Dinner: Impossible?"
