Doctor and Brigadier flee clawing Yeti

Trapped underground in the Dark Tower’s claustrophobic tunnels, the Second Doctor and Brigadier Lethbridge-Stewart face a relentless Yeti hunting them through the rock passages. The Doctor’s quick thinking with a Roman Candle firework momentarily drives the creature back, but their fragile reprieve shatters when the Yeti triggers a rockfall that blocks their exit. As daylight flickers in a sliver near an unexplored door, the Brigadier’s grim realization settles: they have escaped the hunting beast only to be sealed inside, sealed with an ominous invitation to press forward into the unknown depths of the Tower.
