This is one movie I'd love to get my hands on (sadly, it has not been released in any format in Australia, and is not going to be).
Allegedly, it's a historical fiction based around the "discovery" of the lobotomy in America in the 1950's, when the lobotomy was seen as a cure-all for mental patients. Plotwise, from memory, Meat is a gangster whose girlfiends wants a lobotomy, and I believe (but don't quote me) she has some sort of tryst with the doctor. But do NOT quote me on the last bit.
The lobotomy bit sounds fun though.
