COLD LIGHT OF DAY

In late-1970s London, middle-aged civil servant Jordan March, apprehended by authorities, recounts the various murders he committed to Inspector Simmons, which are relayed through flashbacks. Jordan's killing spree began with a young former art student, Joe, whom he meets at a pub. After the two have drinks, Joe returns home with Jordan. Jordan finds Joe attractive, agrees to let Joe stay in his flat until he can regain stability. The next morning, Jordan spies on Joe as he takes a bath. Joe and Jordan have coffee at a cafe, but their conversation soon turns contentious. After Jordan departs for work, Joe cruises a young man for sex in the cafe bathroom.

Jordan soon become possessive of the young and freewheeling Joe, who gradually unabashedly takes advantage of him. One morning, while Joe lies sleeping, Jordan strangles him to death, before collapsing atop his body. He then experiences a flashback of the death of his grandfather as a child.

He keeps Joe's corpse in his bed, engaging in necrophilia with the body. Later, while walking through a red-light district, Jordan is approached by a female prostitute who ushers him into her flat. She attempts to seduce him, but he rebuffs her efforts; nonetheless, he pays her for her efforts before nervously departing.

Later, Jordan returns to the cafe and is approached by a young homeless man who asks for a cigarette. Though Jordan is annoyed, the man manages to convince Jordan to let him stay with him. Once at his flat, Jordan attacks the man, strangling him as he sits in an armchair before drowning him in his bathtub. After the murder, Jordan falls into a drunken sleep, and has nightmares about his grandfather's death, which he witnessed as a child. The following day, Jordan dismembers and skins the man's corpse, flushing heaps of flesh down the toilet, and boiling his severed head.

Jordan encounters another young punk, Stephen, on the streets of London, and saves him from a drug overdose. Stephen returns with Jordan to his flat, where he locks himself in the bathroom and injects himself with heroin. After stumbling out of the bathroom, Stephen collapses, suffering another overdose. Jordan proceeds to strangle him to death with a belt.

The next day, Julie, another tenant who lives beneath Jordan's flat, finds her bathroom plumbing appears to be clogged, and phones the landlord to inspect it. She informs Jordan of this, which causes him to panic. Jordan brings pieces of Stephen's flesh and organs outside, where he disposes of them in a storm drain. Meanwhile, the plumber inspecting the building notices a stench of decay, and finds remnants of human flesh in the pipes, leading him to contact the police. Jordan is arrested, and his flat dismantled by police. Beneath the floorboards, they uncover Joe's corpse, along with the dismembered bodies of the two other men.

Jordan is arrested after human remains are discovered in his building’s drains. Police uncover multiple corpses in his flat.

The conclusion delivers the grim fallout of Jordan’s crimes, as his compulsion leads to his inevitable capture. The film closes not with spectacle, but the banality of evil—his killing spree unraveled by something as mundane as clogged plumbing, underscoring both the horror and the inescapable consequences of his actions.
