The Beast in the Cellar (1970) Timeline Explained – Every Event in Order

Joyce and Ellie kept Steven locked in the cellar to prevent him from being called up for military service during the Second World War. After their father returned from WWI as a shell-shocked, violently unstable man, Joyce was determined to protect Steven from ending up like their father. With WWII beginning, she feared Steven would be conscripted and suffer the same psychological breakdown, so she and Ellie drugged him and confined him in the cellar.

Foreshadowing: The sisters' decision is foreshadowed by their intense fear when soldiers begin dying near their home, as they immediately suspect their brother.

Steven dug a tunnel out of the cellar over time, allowing him to slip in and out of the house undetected. This tunnel confirmed the sisters' worst fears that Steven was the one leaving the house and attacking the soldiers in the surrounding woodland.

Foreshadowing: The discovery of the tunnel follows the mysterious killings that puzzled investigators who suspected a wild animal.

Steven's hatred of uniformed soldiers developed over decades of confinement and abuse in the cellar. The sisters continuously drugged him by lacing his water with sleeping pills to keep him subdued. This prolonged imprisonment and loss of freedom, combined with his father's violent history as a soldier, warped Steven into a savage state who blamed soldiers for his captivity.

Foreshadowing: The seeds of Steven's hatred are visible in his attack, which targets the military legacy represented by his father's photograph.

Steven wore their father's army overcoat and cap when he returned to attack, symbolizing the destructive military legacy that haunted the family. This outfit connected Steven's violence to his father's past and the war trauma that shaped his entire life.

Foreshadowing: The sisters' history with their father, a violent WWI veteran, establishes why this specific clothing choice carries such symbolic weight.

• steven attack

Ellie realized after Steven was shot that he was not trying to harm Joyce directly. His attack was directed at a framed bedside photograph of their father in uniform. Steven's violence was a misguided expression of anger toward his father's military legacy and the life it stole from him.

Foreshadowing: This revelation reframes the attack as Steven finally confronting the root cause of his suffering: his father's military influence on the family.

Ellie decided to call the authorities after Joyce suffered a fall and became bedridden, leaving Ellie to manage everything alone. With the discovery of a soldier's body on their property and the tunnel confirming Steven was the killer, Ellie realized she could not handle the situation by herself and needed help.

Foreshadowing: This decision marks a turning point where the sisters' decades-long secret finally becomes impossible to maintain.

The father returned from the First World War as a shell-shocked veteran, suffering from severe psychological trauma that made him violent and unstable. This trauma cast a dark shadow over the family and directly influenced Joyce's desperate decision to protect Steven from military service.

Foreshadowing: The father's trauma establishes the family pattern of violence connected to war and military service.

The sisters drugged Steven regularly by adding sleeping pills to his water, keeping him subdued and unaware enough to remain hidden. They maintained this secret after their parents died, continuing to confine him in the cellar while living in the house above.

Foreshadowing: The method of confinement explains Steven's transformation into a savage state after decades of drug-induced stupor.

• sleeping pills
• drugged
• concealment
• cellar decades

Joyce was determined to prevent Steven from being conscripted because she had witnessed what the military had done to their father. Having seen her father return from WWI as a broken, violent man, she believed military service would destroy Steven the same way, so she took extreme measures to protect him.

Foreshadowing: This motivation reveals how the father's war trauma created a cycle of protection that became its own form of abuse.

The exact trigger is not explicitly stated in the summary, but Steven's return appears to be driven by his growing rage and the tunnel providing him access. When the sisters began filling in the tunnel to trap him inside, Steven likely felt compelled to make one final confrontation, especially after years of pent-up hatred for the family and soldiers.

Foreshadowing: The sisters' attempt to seal the tunnel directly precedes Steven's violent return.

• steven returns
• confrontation
• final attack

The soldier shot Steven because he was attacking Joyce while wearing their father's army overcoat and cap, appearing as a violent threat in the moment. The soldier acted to protect Joyce from what appeared to be a dangerous attacker, not knowing Steven was the sisters' brother.

Foreshadowing: This tragic ending stems from the sisters' decades of concealment, which prevented any possibility of a peaceful resolution.

• soldier shoots steven
• fatal shot
• death climax

The film shows how WWI trauma passed through the family: the father's violence created a fearful environment, Joyce's overprotective response locked Steven away for decades, and Steven's resulting savagery led to murder and his own death. The violence and damage caused by war reverberated through three generations, ending in tragedy.

Foreshadowing: The entire narrative traces how one generation's war trauma poisoned the next, creating a cycle of abuse and destruction.
