Friday the 13th

John and Christine have invited two of their friends for dinner in their London home. Natalie arrives without her husband, distraught, having just heard that the plane bringing him home crashed at sea. With the potential widow they wait with baited breath for news confirming whether her husband is among the survivors ...and learn that they are the winners of that evening's super jackpot lottery draw.
From then on, the operative words are "controlling emotions". And that is just the beginning of this eventful evening, with twists, turns and revelations galore.
