Deep in the remote Glyderau mountains, a rock crushes a man's leg and his friend faces an agonising decision, stay by his side or go for help; an injured woman is found on the hillside but fights every attempt to carry her to safety; and a father and son, lost in thick mountain mist, get an unexpected lifeline from a stranger passing at just the right moment; three different rescues, each one pushing the teams in different ways.

Rescuers are searching for an injured man who may have taken hallucinogens, someone with no sense of the danger he is in and no ability to help himself be found; two climbers are trapped on a sheer ledge with darkness closing in and no torches between them; and a family takes a wrong turn on one of Wales' unforgiving peaks, turning a day out into a frightening ordeal; the teams have seen a lot, but tonight throws them something different.

Multiple teams mobilize to reach a seriously injured man trapped in dense woods in South Eryri, racing against time through difficult terrain; thick fog rolls in without warning and swallows two hikers whole, leaving rescuers searching blind; deep in the ridges of a remote mountain, a lone woman has disappeared into terrain so complex that even a helicopter struggles to spot her; it's one of those shifts where everything is hard and nothing goes simply.

A serious crash in a remote location triggers a full multi-agency response as emergency teams converge on an isolated mountain road; a rescue helicopter winches a critically injured woman from the floor of a steep and treacherous gorge in a technically demanding operation; and at a local race event, a team of volunteers expecting a routine day suddenly find themselves responding to an emergency no one saw coming; high stakes across the board.
