The Increasingly Poor Decisions of Todd Margaret is a black comedy television series starring David Cross, Sharon Horgan, Blake Harrison, Will Arnett, Spike Jonze, Sara Pascoe and Amber Tamblyn.

The first two seasons of the series tell a single story—that of American office temp worker Todd Margaret (David Cross).

Todd is put in charge of Thunder Muscle, a new energy drink his company is seeking to sell in the United Kingdom.

During season 1, a cold open at the start of each episode depicts Todd before a British court as various charges against him are read out.

For the bulk of season 1, Brent is shown as a foul-mouthed, abusive superior towards Todd, constantly demanding unrealistic results in terms of timetables for getting Thunder Muscle onto the British marketplace.

In the end, Brent attempts (and fails) to defend Todd in court as Doug discovers that Mountford is Dave, the son of a rich and powerful Lord.

Mountford, Sr. also reveals that Todd's American citizenship has been revoked on account of his actions, and the only countries that are willing to take him are the Turks and Caicos Islands and North Korea.

Todd pushes the button, bringing about a nuclear holocaust that seemingly destroys the rest of the world as well as all of the other characters, with the notable exception of the lone survivor, a Turkish terrorist who wanted to blow himself up in an act of terrorism during the course of the series—as he notes in the final line of the season, "There is a certain irony to [it]."

Gradually, the new Todd becomes aware of the events from previous seasons and tries to make changes to prevent his destiny to destroy the world with North Korean red button.

Finally Todd accepts the inevitable and presses the red button, only for the "North Korean army" to be part of an elaborate game show.

Part-time office temp Todd Margaret is unexpectedly chosen to lead the UK launch of Thunder Muscle, a new North Korean energy drink of suspicious contents.

High on morphine, Todd mistakes a small teddy bear for Hudson, Alice's former boyfriend, whom he rightly suspects of trying to win her back.

Desperate to make it to La Molecule before Hudson, Todd steals a test tube of toxic spores on the way.

Scenes from the first episode were re-shot after the Channel 4 airing when the part of Margaret's assistant, Dave, was recast with Blake Harrison.
