When a cyclist is crushed by a 20-tonne lorry, paramedic David Hastie and student paramedic Esme Jenkins rush to Leamington Spa. At the same time, in Coventry, paramedic Chelsie Kennedy and technician Simon Lees treat a man who has fallen from a barge. Paramedics also race to save a two-month-old baby reported to be in cardiac arrest - but two ambulances and four police cars are struggling to find him.
