In 2019 Omega Sector joined MIG operative Ian Young to catch the Engineer. He works alone, and Maria and Luther are nearby if needed.

Maria and Luther kiss, and then they hear that Ian is down.

In the present time, Harry and Helen are struggling financially and have plumbing issues.

Gib briefs everyone they have a lead on the engineer. Luther acts strangely because he and Maria broke up after that mission.

The group is headed to Austria and will be undercover at a casino. They must get Peter to lose his money and lead them to the Engineer.

Helen isn't used to wearing fancy clothes and thinks they could use the money to fix the plumbing. Harry tells her to enjoy the fantasy.

Luther won't give up asking Maria why they broke up and if they were a good team.

Helen and Peter's date, Tiffany, hit it off. Helen switched their identities and pretends she's the businesswoman and Harry is a model.

Peter gets frustrated that he keeps losing. Luther is dealing at the blackjack table.

Outside, Peter loses it, and Harry offers to get him the money, hoping it will lead them to the engineer.

The next day, Harry and Helen take Peter the money and find him murdered with a note.

Helen realizes the Engineer was the guy with bad hair who was watching Peter.

Gib sees on surveillance that the Engineer is leaving the building, and a car chase begins.

Luther and Maria get injured trying to stop the Engineer's truck. Harry stands on his car and jumps into the Engineer's. He strangles him until the car stops.

Maria finally admits to Luther she did care about him, but he passed out from the drugs.
