春休み
Jacki (Geeson) and Julian (Potter) Dewar, a pair of fraternal twins, arrive via bus in London on Spring break from university, while their father is in Mexico on business. The pair launch themselves into London's underground party scene, clubbing at strip bars, accompanied by Jacki's teddy bear, Agamemnon, whom the twins address—and regard—as a father figure. At one club the pair encounter Clive, a small-time pimp who survives by ingratiating himself with the wealthy and well-connected. Clive quickly endears himself to Jacki, while Clive's sometimes girlfriend Denise attempts to seduce Jules. Julian turns her down, intent on beginning an incestuous relationship with Jacki. Julian regards he and his sister as two halves of a hive mind, and sees incest as a natural expression of their closeness.
