Friend of the Family, A

The London family is in crisis.

Newly-divorced Tony is fantasising about someone he shouldn't.

Prize-winning writer Sean has a hot new girlfriend, and a dose of writer's block.

Their brother Ned has just come back from Australia, leaving his girlfriend behind.

And now they have a new lodger - a mysterious stranger.

But is he the friend this family needs, or a troublemaker they could do without?
