Hubert Flynn (Pete Postlethwaite, Amistad, The Lost World: Jurassic Park) enjoys the three loves in his life: his nightly beer at the local bar, betting on the horses and his eccentric wife Conchita (Imelda Staunton, Shakespeare in Love, Sense and Sensibility)—in that order. So when he comes home one night and turns into a rat, Conchita is not so quick to forgive.
When a local reporter offers to write a book on the family's plight, Conchita seizes the opportunity to cash in on her experience as the wife of a rat, and therein begins the family's struggle between the love of money and the love of their father. Coping with their new family life creates many hair-raising adventures for poor Hubert—being banished to a farm, thrown into a washing machine, locked in a refrigerator—and it isn't long before they all begin to long for the good old days, no matter how bad they were!
Rat is filled with hilarity that will make you want to smile and say, "Cheese!"
