When Patrick Jane and others are taken hostage by an armed man accused of murder, Jane must think quickly to defuse the situation.

Krane attacks Leo, Douglas and Principal Perry. Leo's arm is badly injured. It can't be saved so Douglas implants bionics into it. An epic battle with Krane ensues.

Fourteen-year-old Leo and his newfound siblings, a trio of superhuman teens, together learn to navigate a typical high school with not-so-typical bionic glitches.

With bionic Victor Krane's help, Davenport's evil brother Douglas has enabled the Triton app and gained control of the Lab Rats.

Leo and Tasha are kidnapped by Krane, which sends Davenport on a rescue mission and sets up a showdown that puts Krane head to head with Adam, Bree and Chase.

When the Lab Rats are caught on video using their bionics, the video goes viral and their secret is revealed. Government agents arrive and place the house on lockdown.
