Everything ​can change in the blink of an eye. . .

On an ordinary London afternoon, a truck swerves across five lanes of traffic and creates a tangle of chaos and confusion. As loved ones wait to hear news and the hospital prepares to receive the injured, a dozen lives hang in the balance. A doctor is torn between helping the injured and hiding his young mistress; a bridegroom hopes to get to the church on time; a widow waiting to reunite with a lost love ponders whether she’ll ever see him again; and the mysterious hitchhiker, the only person who knows what really happened, is nowhere to be found.
