Singer and actress Marianne Faithfull plays a grandmother in dire straights who becomes a sex worker in London's seedy Soho, in a touching yet hilarious movie that has lit up a hitherto subdued Berlin film festival.
"Irina Palm" follows Maggie, played by Faithfull, from the side of her sick grandson's hospital bed to a sex shop where, desperate to pay for the boy's medical treatment abroad, she accepts a job where her smooth-skinned hands are a key asset.
Taught by a younger woman, she learns to service clients who stand on the other side of a wall with a hole in it where they can be heard but not seen.
So legendary is her technique that queues of customers begin to form, a rival club seeks to poach her.
Much of the comedy derives from the horror etched on Faithfull's face as she goes to work, and the reaction of her straight-laced circle of friends when they discover what Maggie has been up to during the day.
Actually, scratch that sequel, don't even want to think about it.
