Well, it looks like Station 118 has a good ol' fashioned bank heist on its hands.
The stakes were low…well, up until those few final minutes WHICH WE WILL GET TO.
First, let’s set up this heist situation.

It’s Franklin Prentice’s last day as bank manager before his retirement.
Before he can officially retire though, he has one last armored car delivery to get through.
Not in the protocol?
Billy foaming at the mouth and seizing on his way out.
Immediately followed by Franklin foaming at the mouth and seizing inside the bank vault.
Apparently, Franklin’s retiring in a blaze of glory!
What does our fearless Hen do?
So, you know, just your very typical work day all around.
Their first priority is to get some more oxygen inside the vault.
Great, at least one thing is going their way.
Next, the team needs to, well, they need to break into that bank vault.
No one dons a Danny Ocean tuxedo to do this and that seems like a real missed opportunity.
No, instead, Bobby calls a contractor he thinks might be able to help: Michael Grant.
Thank goodnessthose two made up last weekotherwise there’s no way Michael would agree to help.
But they did makeup and Michael will, FOR HEN, help.
Quit complaining, Michael!
The news also makes 118 panic a littlethey want to get to Hen ASAP.
Because just as 118 is returning to the firehouse, the cops show up.
They’ve been tipped off that there is $300,000 in bags inside the firetruck.
And you guys,there is $300,000 in bags inside the firetruck.
Our firefighters have some explaining to do!
And thus begins the interrogation montage where we learn so many things!
That last thing seems weird, but it will be important later!
It’s all getting very confusing!
It must have been Franklin!
was cut while the firefighters worked on getting through the vault door.
IT WAS DEFINITELY FRANKLIN.
When the cops arrive at Franklin’s house, they find him dead on the floor.
But alas, the diamonds are nowhere to be found.
Did someone murder Franklin and take the diamonds?
Did he have an accomplice?
The searches don’t turn up anything.
She knows who the accomplice is.
She figures it must be scorpion poison because, sure, and she’s right.
I mean, good for Marty for turning a bit firetruck ladder repairman role into bank heist mastermind.
As it so happens, Marty and Franklin were brothers-in-law at one time.
Since Marty knew everything regarding fire rescue protocols and Franklin knew everything regarding bank stuff, they teamed up.
Like I said, Franklin was retiring in a blaze of glory.
It’s the Captain of the LAFD.
