Bliss follows the complicated double life of Andrew, a successful travel writer who, through extenuating circumstances, finds himself living between two sets of wives and children whose existences are unknown to each other.

Andrew, in a constant state of moral crisis, must find a way to balance his time and energies between his wife Kim and teenage daughter, while travelling back and forth across Bristol to his other family, wife Denise and their teenage son.

As Andrew's two worlds become ever harder to contain, so does his sanity. And he finds himself going to increasingly drastic lengths to protect the two families he loves.
