Home is where the heart is -- but also the danger, if you're Veronica Mars.

The private investigator is back in Hulu's new "Veronica Mars" Season 4 trailer. It teases her return to Neptune after a decade, and it's nothing short of explosive. While the preview starts off with a lot of sunny spring-break fun, it quickly takes a turn. A literal bomb goes off, as we saw in the first teaser, and just like that, Veronica (Kristen Bell) has someone dangerous to track down.

There seems to be a campaign against Neptune, and it involves spring breakers being murdered. The description notes that this is a "mystery that pits the enclave's wealthy elites ... against a working class that relies on the cash influx that comes with being the West Coast's answer to Daytona Beach." We're intrigued, especially since we get to Veronica and several other familiar faces back in action. Watch below.

"Veronica Mars" Season 4 premieres July 26 on Hulu.
