Sisters (1973) Timeline Explained – Every Event in Order

Danielle attacks and kills Philip with the birthday cake knife from the cutlery set he gave her. The murder appears to be driven by her fragile mental state, influenced by her dependency on the red pills that Philip unknowingly disposed of. When she woke up feeling unwell and discovered only three pills remained, the loss of her medication (which she needed but could no longer access) destabilized her further, triggering the violent outburst.

Foreshadowing: Earlier scenes establish Danielle's deteriorating mental state and her reliance on medication, with tension rising between her and Dominique over Philip.
