When a woman dies in a supposed accident, her parents suspect their son-in-law of foul play. When the police begin to agree, the murder suspect vanishes.

Mark Schall kills his mother-in-law and wounds his father-in-law in the middle of the night, then turns himself in. He claims, however, that he cannot remember the crime itself. His defense team finds evidence that suggests the crimes were committed while Mark was sleep walking. They build their defense around this theory.

A fanciful battle of the sexes ensues when the relationships of the staff and patrons of a quirky London café are unexpectedly turned upside down by sudden revelations of terribly embarrassing secrets having to do with their sexual misadventures. The food is not that good, but you can be yourselves and show yourselves for what you are: maniacs, perverts, gays, cheaters, violent old women, cross-dressers, whining singers, broken hearts... Come in, there is room!
