Jack, a totally self-centered and immature dude, is abducted and brought to an alien zoo to replace his recently deceased father - a father he thought had abandoned him as a child. But Jack's selfishness immediately clashes with the tyrannical alien zookeeper, as well as the collection of humans from different time periods who are now his new roommates. Alongside an over-the-hill Roman gladiator, a repressed '50s housewife, a rocker hillbilly from the '80s and a handful of other misfits, Jack will struggle with the world's weirdest daddy issues and maturing as a person.
