Hapless filmmaker Simone is directing a no-budget porno-Western that features married couple Simon and Eva. During a water torture scene, Eva is unable to perform fellatio on Simon. Simone breaks off from the shoot to perform mobile phone roleplay with Dean, which goes wrong.

In a hotel room, Roland, who has won the lottery, pays for sex with Dean. Dean confesses his love for Roland. Simon is also paying for sex with Dean, and they are interrupted from a post-coital argument by Eva. In front of Eva, Simon makes a nuisance phone call to Crisis Line UK, a Samaritan-style call centre.

Simon is working a shift at Crisis Line, where Roland also works. Eva appears to contact Crisis Line because she has asphyxiated her husband. On the porno-Western set, Dean visits Simone. Instead of paying him for sex, Simone asks Dean to perform mobile phone roleplay, which goes wrong. During a water torture scene, Eva is unable to perform fellatio on Simon.

'Rococo 55' is a circular semi-feature film that plays endlessly in the gallery space. The film is structured into five sequences that are connected by a series of slow dissolves and multiple (and absurd) mobile phone calls.
