Ok I strongly remember this being called something else bc I posted about it here ages ago.
Spenser — an ex-cop better known for making trouble than solving it — just got out of prison and is leaving - where the fuck else, do you see who stars in this? - Boston for good. But first he gets roped into helping his old boxing coach and mentor, Henry, with a promising amateur. That's Hawk, a brash, no-nonsense MMA fighter convinced he'll be a tougher opponent than Spenser ever was. When two of Spenser’s former colleagues turn up murdered, he recruits Hawk and his foul-mouthed ex-girlfriend, Cissy (Iliza Shlesinger), to help him investigate and bring the culprits to justice.
Anyway, here's Mark Whalberg (Forgives himself), and Winston Duke ("Us", "Black Panther"). There's also Post Malone ("music") and Alan Arkin (That show noone watches but keeps being nominated).
Watch it (or not) March 6th.
