The stage is set for corporate sabotage when Staci sends the Boss Baby undercover to take down Baby Corp's latest leader at a company retreat.

Halloween is the perfect cover for the Boss Baby and his costumed field team to sneak into the belly of the beast. But Staci's got plans to stop them.

The Boss Baby declares war on a new threat: a popular TV show starring a pygmy goat, a tamandua and their human handler.

After sneaking into a grown-up movie, Tim decides he's mature enough for the adult world. Meanwhile, Boss Baby sleeps over at a friend's house.

The Boss Baby's away at a checkup, so it's up to interim manager Staci to fend off three wars: one from Pyg & Tam, one from OCB and one from Bug the Pug.
