There's some death-defying Halo-style jumping, a scrap on a bridge with Natasha Romanoff's looking distinctly Stormtrooper-esque, some fiery explosions and pleasant family bonding.
Nat's old family comprises Florence Pugh's Yelena Belova, Russian super soldier Red Guardian (aka Stranger Things star David Harbour), and another Black Widow, Melina Vostokoff, played by Rachel Weisz.
They'll all be pitted against villain Taskmaster, with Ray Winstone also on the bill, along with William Hurt's Thaddeus Ross and a reported cameo from Robert Downey Jr's Tony Stark too.
The action picks up after Captain America: Civil War, but before Avengers: Infinity War – so it does mean that Black Widow gets out of this on alive, we can't speak for the rest of them.
Disney also launched four eye-catching character posters for the film, that you can check out below.
It lands in the UK on 1 May.
