Lucy (Demi Moore) is the egotistical CEO of Incredible Edibles, America's premiere provider of edible cutlery. In her infinite wisdom, Lucy leads her staff, including her long-suffering assistants, Freddie (Karan Soni) and Jess (Jessica Williams) (Jess is working on a marketing campaign for Lucy, which Lucy simply is not satisfied with and constantly berates) , on a corporate team-building caving weekend to New Mexico.Both Jess and Freddie think they are in the running for a promotion to VP. At the very last minute, Lucy switches to the advanced hiking route, while their guide Brandon strongly suggests that they should take the beginner's route. Aidan (Calum Worthy) is the group intern and has wet his pants. Suzy (Nasim Pedrad) is absolutely terrified and begs Lucy to not include her in the trek. May (Jennifer Kim) has recently taken over accounting and is doing a shoddy job and is gently prodded on the same by Gloria (Martha Kelly).Freddie tells Jess that Lucy is playing them against each other as she needs both of them performing at their best to keep the company afloat as one of their major accounts has been leaking money non-stop.When disaster strikes (an earthquake), not even their useless guide Brandon (Ed Helms) can save them. Brandon dies when the only exit tunnel collapses with him inside it. The group has no escape, very limited food and low water supplies. Billy (Dan Bakkedahl) is furious that he was made to give up his water supply just because he came prepared.Lucy reckons they will be rescued in a few hours and designates a toilet area and a private area in the cave. May and Suzy are lesbians and use the private area for sex. Day 1 comes to an end when Lucy tries to give Freddie a blow job (apparently, they do this to each other), but Freddie is angry with Lucy for playing him against Jess and refuses to be her sex toy anymore.Day 2 starts when Gloria accuses Lucy of being a complete bitch. Jess and Freddie pile in when they reveal that Lucy's latest account (Vanderson Wealth Trust) are losing money and soon the company won't have any money left. Freddie and Jess also accuse Lucy of stealing any good ideas they come up with. Freddie says that he came up with the idea of edible cutlery, and before that Lucy used to sell beauty products.Day 5. Aidan had a leg injury which is now smelling badly. The group is out of food and water. Freddie suggests eating Brandon. The group has an intense debate, but Lucy is against consuming another human being. Everybody votes and they decide to eat Brandon. Billy finds that one of Brandon's arms is missing and eventually they find it in Lucy's possession. She was trying to keep Brandon all for herself. Suzy reveals that she had sex with Brandon days before the office trip. It is also revealed that Lucy didn't file the paperwork for the trip with the rangers, like she said she did. and thus, nobody now even knows that the entire team is missing and where.Soon Brandon is completely eaten away. The battery in the case runs out. Aidan says that he has a lamp that uses the kinetic energy generated from the wanking motion of his hand into light. Freddie decides to lead Jess and Billy further down the cave system to try and find a way out. They find water inside the cave, and when Freddie and Billy drink it, they totally flip out on hallucinate. eventually their headlamp dies, and they make their way back to the cave where the rest of their team is.Day 9: Aidan has gangrene in his leg now. Gloria writes a will saying if she dies everyone can eat her except Lucy. Lucy and Gloria don't like each other from the beginning of the trip. slowly the whole group turns against Lucy, when they learn that she hired them (all minorities) because the company got money from the minorities commission for her affirmative action. Lucy is badly injured when a fight breaks out and she trips and falls headfirst on a rock. Just moments later they are about to be rescued. Lucy tells Freddie that she will jail the entire team once they get out. Jess rallies everyone and finally the gang teams up to kill Lucy.When the press interviews them, the team replies that a rock fell on Lucy while she slept.
