Catastrophe

As Rob and Sharon celebrate what is a tainted wedding anniversary, Fran and Chris are sadly drifting further apart.

Chris - now living out of a rented flat - has an exotic sexual itch that he's determined to scratch. While Fran has thrown herself into an ill-conceived relationship with Patrick - a film producer who proves himself to be a very fast mover.

Elsewhere, Dave's flourishing love affair with Catherine - a high achiever he's met through AA - is gathering momentum.

Unfortunately when Catherine invites Dave to spend the night with a group of 'sober friends', Dave's tale of redemption proves a little dull for their extreme tastes. Their subsequent argument and break up tests Dave's dedication to his sobriety.
