A dry thunderstorm rolls over Los Angeles, bringing in a series of lightning strike emergencies for the 118 and leaves a first responder's life hanging in the balance; Chimney get a surprise from a visiting Albert.

The 118 responds to a skydiving trip gone wrong. A bank rep is injured in a home repossession, a lovestruck assistant's lunch run ends in disaster, and Athena and the family come to terms with Michael's difficult health decision.

The 118 races to the rescue when the call centre goes up in flames; Bobby risks his life to save a trapped May and Claudette; Buck and Eddie must help an injured electrician; Chimney and his brother team up as firefighters for the first time.

As Buck's life hangs in the balance, he dreams of a world where he never became a firefighter, for better and worse.

The 118 races to rescue a little girl in a runaway hot air balloon and help with a city power outage caused by a hijacked tree-trimmer truck. Athena's investigation into the serial rapist case puts her life in jeopardy.
