Detective Jeff Slade (Michael French - EastEnders) and Science Officer Holly Turner (Chloe Annett - Red Dwarf) solve crimes unlike other cops. With access to a time machine, they can travel back in time to gather the crime scene evidence they need to crack their cases of murder, kidnapping and robbery. Desperate to keep the time machine a secret, the dynamic duo lie to cover up how they can be in two places at once, they dodge their skeptical boss's questions and most importantly - they must return to the machine before time runs out - or be forever lost in a loop of infinity.
