Tough Love: Part 1

Lenny Milton is an unambitious officer whose best friend, Michael Love, is now head of the local force. But when Milton is forced undercover by the police complaints department to investigate allegations of corruption against his friend, he faces uncovering a truth he desperately doesn't want to learn. Meanwhile, the body of a young boy is found at the bottom of a stairwell, but Milton is convinced that his colleague, Singleton, is side-lining the investigation, and when evidence related to the case goes missing from his desk drawer, he suspects that it is not just Love who may be corrupt. Later, Milton arranges to meet one of his colleagues for a drink, but is caught off guard, and his drink is spiked. He awakes many hours later next to the dead body of one of his informants, who has been bound, gagged and strangled. Milton's colleagues refuse to believe his version of events, and he is arrested and detained on suspicion of murder.
