Hawaii Five-0 will be in a tight spot during "Ku I Ka Pili Koko (Blood Brothers)," a fact which does not bode well for the highly claustrophobic Danno.

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

When Five-0 acts on a bad tip, the day will take a nasty turn for McGarrett (Alex O'Loughlin) and Danny (Scott Caan). An explosion will leave the latter injured while the duo remains cut off from any outside help.

"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," teased executive producer Peter M. Lenkov, according to TV Line.

Don't worry, however, the drama won't be without a bit of comedy. While it may be impossible to have a car-gument while trapped under the rubble of a former parking garage, Danno and McGarrett's strikingly different personalities will manage to create humor in even the most dangerous situations (see video below).

According to Lenkov, the episode will have everything McDanno fans love.

"Do you like McGarrett? Do you like Danny? Together? If so, you're gonna love #H50 419 tomorrow," Lenkov tweeted on Thursday.
