Joanna tells Laurel she thinks Danny might have been murdered. She shows her evidence that the way he died doesn't fit with the circumstances of the blaze.
Laurel takes evidence to her father. It seems that at least once other firefighter was killed when his suit burned hotter than the fire being fought. Quentin wants to leave it with the fire department. Quentin had the phone he got from Arrow analyzed, but it's a dead-end. Laurel snags the phone and places a call to Oliver, saying "I need your help".
Laurel is visited by Arrow. Using a device to disguise his voice, Arrow tells her he'll "look into" Danny's case.

Back in a flashback we see Oliver hunted by a masked man with a weapon. He seems to be trapped. Arrow arrives at the scene of a fire just after the killer tosses a firefighter into a blaze. Arrow notices a tattoo on his wrist but he manages to escape.
Another island flashback. Oliver tries to attack the masked man and ends up rolling down a hill into a stream. Oliver calls Laurel as Arrow. He tells her what vehicle the killer drives and about a certain tattoo and scar.
John isn't happy Oliver left Laurel by herself to battle the killer. This leads to a brief fight between the two as John tries to figure out what is wrong with Oliver. He thinks the other archer got into his head.
Oliver talks to Laurel about her relationship with Tommy and her not wanting him to have a drawer at her place. She isn't sure she's ready for the step-up in commitment.
Laurel speaks with Fire Chief Raines. She references the fire house that had the Firefly tattoos. Three of them have been killed in the past six weeks. Another member of the group, Garfield Lynns, died 2 years earlier in a famous building fire at Noddel Towers which claimed the lives of dozens of civilians and six firefighters. The fire happened because of faulty building materials. The chief isn't interested in Laurel's questions.
Laurel calls Arrow's phone afterwards and tells him she's at a dead-end. Arrow says "It's my turn".
On the island Oliver wakes up in the water and sees his attacker he fought with is dead.
Thea wants to get her mother out of the house. She's up-set that Moira is no longer acting like her mother.
Oliver talks to John about what happened to him during his battle with the other archer. In past years he'd never been worried about death because he had nothing to lose. But his life is different now because of what would happen to his loved ones if they lose him. John thinks having something to live for should give him an edge. Oliver suggests that perhaps Garfield wasn't actually killed in the fire.
At the benefit Laurel and Oliver talk to Raines about the Noddel fire. He says it was the worst he'd ever seen. Garfield begged him to send his unit back in but he wouldn't do it. Raines doesn't think Garfield could have survived the fire. At that exact moment Garfield shows up behind them and starts setting the place on fire. Garfield covers Raines in accelerant and Oliver runs off. Garfield blames Raines for what happened to him. Just before Garfield can set Raines on fire Arrow shows up. Arrow offers to get him help but Garfield walks right into the fire.
The media is hailing Arrow as a hero. Moira is taking over as CEO and seems to be in slightly better spirits.
Joanna is finally taking a leave of absence. She gives Laurel her brother's badge. She wants her to give it to Arrow as a thank-you. Quentin apologizes to Laurel and gets Arrow's phone back from her. But after a second he rethinks it and hands it back.
We see that a speaker has been placed in the phone. The next time Laurel speaks to Arrow the police should be able to listen in.
Back on the island Oliver has disguised himself in the gear of the masked man. He finds keys and a map.
