Elliot and Stacy spared no expense when it came to renovating their waterfront home, but security wasn't exactly in the budget. The birth of their daughter has forced them to take a hard look at safety. Will Jon scare them into shape?

The only thing that Andy and Beth love more than their kids and dogs are her fabulous jewels and his trove of rare 60's and 70's muscle cars. Like most proud collectors, Andy shows off his "babies" in front of the house, and the crooks take notice.

Janice & Mark just moved into their dream house. But with the perfect cover of a wooded area out back, it's a no-brainer target for our peeping-tom crooks. And they like what they see inside. However, a nosy neighbor may get in the way of Jon's plan.

A high-profile award inspires Mike & Geoff to improve upon their ultra-mini tank, the Badger. The twins test the new, beefed-up Badger against heavy weapons and TNT. To reward a job well done, the twins take the H&H crew on a survivalist trip.

The Howe brothers build an ultra-tough, all-terrain vehicle called Subterranean Rover 1. After falling way behind the deadline, the crew at H&H Technologies has to shift into hi-gear. As the deadline looms, tensions in the shop get explosive.

The US Army asks the Howe brothers to make some big changes to H&H's two hi-speed tanks called the Ripsaws. As the twins wire one of the Ripsaws to operate via remote control, a technical glitch puts their contracts with the Army on the line.

Mike and Geoff are underway on their new amphibious tank, but a Vietnam Vet's email takes them on a detour to build an all-terrain wheelchair. The team's competition to build prototype ballistic armor for the tank has an explosive ending.

Mike and Geoff build Mini-Rip, a smaller version of their famous tank, the Ripsaw. The twins will debut Mini-Rip at a motor-sports event in 2 weeks, but with other projects due and a shrinking workforce, H&H is pushed to the limit to get it all done.

Geoff is inspired to build a concept-vehicle, the "Personal Assault Lander" that can travel on water and land. But trouble fabricating their fleet of Subterranean Rovers has already put H&H way behind schedule. Will Geoff's pet project sink H&H?

Members of a SWAT unit ask H&H to arrange a test of the Badger, the world's smallest armored tank. Only the last explosive test left Badger in shambles. With the added pressure of building three SR-1's, the crew scrambles to resurrect the Badger.

The Howes have a new shop, a new female welder, and a crazy new idea that might revolutionize firefighting. A request from the Army has the team creating a new set of Ripsaw tracks for the sole purpose of blowing them up in as many ways as possible.

The Howes and crew almost break their fire-fighting robot preparing it for testing with the fire department. Mike's Ripsaw weapons demonstration for the Army is a hit and hatches the idea for the Howes' next big R&D gamble.

The Howes take on building and testing a prop vehicle for a major motion picture. Meanwhile the crew moves forward on the Riptide amphibious vehicle, including a dangerous test of its escape hatch system underwater.
