Dominic Arkwright meets people who have made or received life-changing phone calls.

Alex Evans was shopping in an Aberystwyth DIY store with his mum when he took a call from his friend Mark Corbett. Mark said he was on board a ship in the Caribbean and that it was sinking. The radio wasn't working and the only number he could remember was his best friend's.

Alex grabbed a till receipt, borrowed a pen from his mum, and started to take down the details. Both are volunteers for the RNLI, but when Alex heard the name of the vessel in distress there was a moment of hesitation.
