More than anything else in the world, 40-year-old Maud wants her own child. Her yearning is so overwhelmingly strong that it takes over every aspect of her existence. To help her confront her grief and get her life back into perspective, she forces herself to watch happy families picking up their kids from school. On her way home she feels a little better and starts flirting with a man on a bicycle who is waiting at the other side of an open canal bridge. But as the bridge closes, she suddenly sees his little boy sitting in the child seat of his bike. As they pass on the bridge they exchange looks; his exploring, hers confused. At that precise moment a speeding car plows into his bike, throwing the little boy out of his seat and into the murky wants of the canal. Maud is in shock but realizes the child is in the water and jumps in after him. In a physical and emotional underwater struggle, Maud desperately tries to save the little boy until she realizes that she has no choice but to let go of him--along with her deep desire for her own child. On the street everything is back to normal; the only thing that remains of the accident is the wreckage of the broken bike--without its child seat.
