Highcliffe Charity Players return after their incredibly sucessful pantomime with the delightful musical Mack and Mabel. The tumultuous relationship between Hollywood director Mack Sennett and Mabel Normand, who became one of his biggest stars comes to life on stage. In a series of flashbacks, Mack relates the glory days of Keystone Studios from 1911, when he discovered Mabel and cast her in dozens of his early "two-reelers", through his invention of The Bathing Beauties and the Keystone Cops.
