A bromance for the ages, Soul Mates is the story of two kindred spirits trapped in a cycle of death and rebirth. Across four different lifetimes with no knowledge of their past lives, they are forever drawn together as mates.

Mum gives Roger and Thinge their first mission... to entice a young Russell Crowe back to NZ. In other lifetimes, Rocky spots his perfect mate; Dom forages for modelling work; and Dave detests Rob's metal-morphosis.

The Kiwi Assassins take their plot to keep a young Russell Crowe in NZ one step further; Sticks and Rocky engage in the first religious war; and Adrian and Dom pitch their fashion label to an investment bank.

Roger and Thinge must preserve NZ's rights to Fizzy Milk; Dom continues his clandestine vacuum sales job; and Rocky challenges Sticks to the ultimate staring competition.

Rocky and Sticks discuss the age-old question - is it wrong to eat babies? Adrian becomes suspicious that Dom is up to something; Roger quits the Kiwi Assassins; and two fundamentalist creationists visit Travel Time.

Sticks introduces Rocky to the best thing ever, spinning; Dom forces Adrian to return to the carcinogenic luxury of his father's home; Thinge and Mum uncover a dark secret; and Dave goes rogue while Roboss is recharging.
