Danno and McGarrett are in for an explosive bonding episode on Hawaii Five-0.

Danno & McGarrett Get A Bizzare New Car For The 'Hawaii Five-0' Season Finale?

Someone has it out for the island's top crime fighters, and a bad tip will put Steve McGarrett (Alex O'Loughlin) and Detective Danny Williams (Scott Caan) in a tight spot during "Blood Brothers." A shady lead will send the partners into an abandoned building that, unbeknownst to the Five-0 team, is rigged to explode. As time and oxygen run short, the fight for survival heats up.

Executive Producer Peter M. Lenkov has dropped a few hints about the upcoming episode, including the fact that Danno will be sustaining some sort of injury during the blast. Luckily for the New Jersey transplant, his Navy SEAL partner will be there to help patch him up.

"Danny and McGarrett are in a perilous situation where they have to really rely on each other, and that's a real 'blood brother' type of episode," Peter M. Lenkov teased, according to TV Line.

Although the duo are clearly in a life or death situation, fans should still expect the pair's usual hallmarks.

"Turned #H50 419 into the network and studio today. Prediction: Fan favorite. McDanno fans will be MORE than satisfied," Lenkov tweeted.
