For actor Toby Flood, Brighton is the final week of a long tour. One night he is visited at the theatre by his estranged wife, Jenny, who, visibly scared, thinks she is being stalked. She asks Toby, for old times' sake, to find out what is going on.
Alarmingly he discovers a sinister connection with Jenny's new partner. Spurred on by a desire to win Jenny back, Toby begins to ask some difficult questions. Before he fully understands the risks he is running, he finds himself caught up in a mysterious - and dangerous - tangle of family rivalries and murderous intent. Suddenly the prospects for his survival start to look very far from good...
