12+Synopsis
Sherlock Season 4 (2017) brings three new episodes you can watch online on iFILM. John and Mary are expecting their first child — and the cracks forming around them are about to split wide open.
The season opens with a puzzle: someone is smashing images of Margaret Thatcher across London, and the motive is far uglier than political obsession. Episode two pits Holmes against Culverton Smith, a wealthy philanthropist whose private life is a catalogue of harm — possibly the most dangerous opponent Sherlock has faced. Then the finale collapses inward on the Holmes family itself: Mycroft's long-kept secret involves a third sibling named Eurus, held somewhere no one was supposed to know about.
Season 4 is the darkest run of the show, more interested in what made Sherlock who he is than in the cases he takes. Watch all episodes of Sherlock Season 4 online on iFILM.
