Harry Enfield and Billy Boyd star in a brand new, full-cast dramatisation of Douglas Adams' first Dirk Gently book, directed by the award-winning Dirk Maggs.

Dirk Gently has an unshakeable belief in the interconnectedness of all things, but his Holistic Detective Agency mainly succeeds in tracking down missing cats for old ladies. Then Dirk stumbles upon an old friend behaving bizarrely - and he's drawn into a four-billion-year-old mystery that must be solved if the human race is to avoid immediate extinction.

Harry Enfield stars as Douglas Adams' much-loved psychic sleuth, with Billy Boyd (The Lord of the Rings), Andrew Sachs (Fawlty Towers), Jim Carter (The Golden Compass), and Olivia Colman (Peepshow).
