Law & Order: UK

The unfolding tragedy of this episode takes you on unexpected twists and turns as what initially looks like a cot death of 6 month old Alex Raines is later diagnosed as shaken baby syndrome leaving Ronnie and Matt with a murder investigation on their hands. But with many possible suspects - the neglectful mum, the absent dad, the resentful nanny or her short-tempered boyfriend - who should our cops arrest? During the trial, some new evidence comes to light which casts doubt over the prosecution’s case. Pitted against the indefatigable Helena Marsden (Jemma Redgrave), the very framework of this family is pulled apart and James and Alesha are forced to do some investigating of their own. The heartbreaking tragedy of what is uncovered leaves us wondering if there is more than one victim in this case.
