It’s summertime and with it come all kinds of outdoor festivals & concerts. Sometimes, when things go wrong, they go wrong very quickly. As is the case with the 7th episode of The Night Shift’s 3rd season when Drew, Syd & Riley attend the San Antonio Park Festival and an accident with the fireworks truck setting up for the display later that night occurs sending people into a frenzied panic. Drew & Syd frantically search for Riley and once she is found safe, they begin tending to the injured. TC & Topher arrive on the scene to help when one of the drivers of the fireworks trucks informs them that the 2nd truck could go off at any minute. Topher is already on his way to attempt to rescue the other & crew members when the truck explodes sending Topher flying with the force of the explosion. He has his bell rung for a few moments, but when TC reaches him he is able to get back up and continue tending to those who need it. When patients from the fireworks accident flood the ER, the doctors have their hands full as they rush to treat them. A single mom & daughter are among the victims who are being treated. Syd forms a bond with the mom and Riley strikes a friendship with the daughter. Later, Topher begins to develop symptoms as a result from the blast. He is adamant that he is fine, just over tired. TC & Jordan know better and force Topher to undergo tests to determine if he has any unseen injuries. The results show that he has a bad concussion and needs to be placed on desk duty for a while.
