As pregnant Sharon's hormones plague her with waves of different emotions, she has a chance meeting with an old flame, which leads to dinner. Meanwhile, Rob struggles to generate advertising business, since he has very few contacts in London, and begins a clandestine friendship with Chris, who is married to a woman Sharon can't stand.
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.
