Watch SOS: Extreme Rescue with Fubo for $0 Today

S2, EP5 "Before Nightfall"

S2, EP1 "Crushed"

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 very different rescues - each one pushing the teams in different ways.

S3, EP1 "Edge of the Cliff"

An 80-year-old woman is stranded 100 metres down a cliff on Yr Wyddfa with no safe way to reach her.

S3, EP2 "Trapped Underground"

Two teenagers are cut off by an underground lake inside an abandoned mine with floodwater rising around them.
