Sam (Hugh Laurie) and Lucy (Joely Richardson) Bell are a married couple who seem to have it all: good looks, successful careers (as a BBC-TV commissioning editor and agent, respectively), matching motorbikes, and an enthusiastic love life. The only thing they lack is the one thing they want most - a baby. Sam and Lucy's love for each other, the most important thing they both have, will now truly be put to the test ... with surprising results.
