Gordon (Richard Lumsden - Sightseers) is determined that he and best friend Keith (Karl Theobald - Alan Partridge: Alpha Papa) will conquer Wainwright's Coast to Coast Walk from St. Bees in Cumbria to Robin Hood's Bay in North Yorkshire. But when a stray conversation determines that old school friends Steve (Jeremy Swift - TV's Downton Abbey) and Julian (Ned Dennehy - TV's Luther) join them on the trip, their best-laid plans reveal multiple mid-life crises. Downhill is a comedy of errors, a testament to the tragically incompatible and a blow-by-blow account of the highs and lows of decades-long friendships.

Barbie stars as Merliah, a surfer who learns a shocking secret: she's a mermaid! She and her dolphin friend set out for an undersea adventure to rescue her mother, the queen of Oceana.
