Catastrophe Show Summary

A comedy following an Irish woman and an American man who make a bloody mess as they struggle to fall in love in London.

Clumsy lust, instant pregnancy, and genuine disaster provide the foundation for this flaming hovel of a relationship.

In a mess of events always in danger of slipping out of their grasp, Rob and Sharon must also learn to deal with her largely awful friend; his eccentric Bostonian mother; and attempt to navigate the choppy waters of their ever-more-complicating lives.

Can Sharon, "an extraordinarily good-smelling woman" and Rob, "a sturdy love-maker" steer through the increasingly thorny situations they find themselves in and still find time for an emergency shag in a stairwell? Prepare to find out.
