It is Brighton, 1959, and the theatre at the end of the pier is having its best summer season in years. Ronnie, a brilliant young magician, and Evie, his dazzling assistant, are top of the bill, drawing audiences each night. Meanwhile, Jack, Jack Robinson, as in 'before you can say', is everyone's favourite compère, a born entertainer, holding the whole show together. As the summer progresses, the off-stage drama between the three begins to overshadow their theatrical success, and events unfold which will have lasting consequences for all their futures.
